The Sims 4 Community Library. An open source library with a focus on providing utilities and services to the larger Sims 4 modding community. Let's not reinvent the wheel! Upload a mod for Morrowind during the month for your chance to win prizes and unlock some special achievements. As usual, here are the full details from darkelfguy. Genius Teens Can Apply to University. If you have The Sims 4: Discover University you’ll definitely want this mod. It will allow you to let teenagers go to University if they meet a requirement. This can be any sim with a genius trait, or a sim who finished elementary school with an A or currently have an A in high school.

There’s a mod for everything out there. Custom houses, scenarios, new careers, and tons of custom items.

While most Sims 4 mods are made up of content to make the game more interesting, some are just downright weird.

That’s the purpose of this list: to share some of the strangest, funniest, and most absurd mods this side of The Sims 4’s universe.

I’ve made my way to & from the darkest depths of Sims 4 mods to bring you some of the funniest and weirdest ones out there. So let’s get weird with it!

35. The Dirt! On all of your floors!

To start, we have one the weirder building mods out there.

When you think of building in Sims games, it’s usually to build the perfect house of your dreams.

There are even those who use money cheats just to spend their days building the perfect home. I mean, it’s fun right?

Well with The Dirt! On all of your floors!, you’ll be able to place dirty floor tiles wherever you want. Now I’m not sure why you’d want to do that, but you can, so here it is!

34. No More Hugging Trash Bags

Traits are an important part of the game.

Each Sim has traits that affect the way they behave in different activities and situations.

One of those traits is called Recycle Disciple, which makes your sim crazy about recycling.

Now where this gets weird is that apparently, you’ll often find Recycle Disciple sims lovingly hugging trash bags when left idle for a while.

Okay fine, this one’s sort of a cheat, since it actually removes some of the weirdness from the base game – but it still makes the list because why the hell would anyone hug a trash bag in the first place?

33. Sleep Naked Mod

I get it, what you do in your own home is your business.

I also get that there are advocates for sleeping in the nude, as you’ll probably find from a simple Google search.

Well if you’re a believer, this mod let’s your sim go to sleep in their birthday suit.

All you have to do is order your sim towards the bed and there’ll be an option to sleep naked – simple as that.

But it doesn’t end there, as sims who sleep naked actually receive a “restful sleep” buff, giving them +2 happiness.

The mod even opens up a whole new list of actions related to sleeping naked, where you can recommend it to others, and even ask other sims if they’ve tried it before. C’mon man…

32. Better Fart Sounds

Let’s just say it: this one’s for those who find farts funny.

In all the hours I’ve spent goofing around in The Sims 4, not once did I think that the fart sounds were lacking.

If you did though, well…there you go.

31. Psychic Sims!

Since Maxis has introduced vampires, spellcasters, and mermaids into the game, modder Lumpinou felt that human sims ended up drawing the short straw.

He aims to balance things out a bit with his mod Psychic Sims!, which basically allows you to make your sims psychics.

Psychic sims have certain powers like dispel negative emotions, commune with the spirits, or even bestow psychic powers onto other sims.

Reactions from other sims have been added as well, where they can either request for your psychic insight or just mock you about your so-called abilities.

30. Bigfoot Head and Body

There are unlimited options when it comes to custom content.

Some have posted recreations of their favorite TV and film characters like the Game of Thrones cast, the Joker, or even stuff from cartoons or video games.

On the other hand, there’s Bigfoot.

This one probably isn’t as common as some others, as I doubt many Sims 4 fans would go online and search for a Bigfoot skin on purpose.

No judgement though, if you want it, go ahead and grab it.

29. Reptilian Body, Head, and Teeth

While we’re on the topic of weird creatures in The Sims 4, here’s another one for you.

Maybe Bigfoot needs a friend. And who better to fill the slot than this strange reptilian creature?

Now you can have two mythical creatures running around your neighbourhood!

This mod lets you create a complete reptilian character with the body, head, and teeth skins included.

28. Extended Butt and Hips Sliders

This mod actually expands on the butt and hip sliders during character creation.

So you’ll have more control over how your sims look, at least in regards to junk in the trunk.

If you’ve ever wanted a bigger butt, well here’s your chance.

The slider allows you to change butt size both vertically and horizontally, and maxing out the values are sure to give you some weird-looking results.

27. Mermaid Hybrid Stabilizer

Ah, mermaids.

What was once a realistic life simulator now lets you become half-human half-fish, just by ingesting Mermadic Kelp.

Apparently, hybrid mermaids were broken in the game. As they weren’t able to switch between fins for swimming and feet for walking.

This mod fixes that. So if you do choose to play as a mermaid, everything should work according to plan.

26. Experimental Recipes on Normal Stove

I’m not sure about you, but I never really got the concept of high-end fine dining restaurants.

You pay way too much money for a plate that’s barely filled with anything, and what you get are dishes with names you’ve never even heard before.

Well that’s just me though, and this is The Sims we’re talking about.

If you wanted, you could cook some gourmet meals yourself from the comfort of your own home.

This mod lets you prepare anything from “Savory Bacon Love Petals” to “Vanilla Sea Shells and Chocolate Caviar” (whatever those are).

25. The Mushroom Chair

The Mushroom Chair.

I’m sure this is one of those mods that we’re just taking out of context. But are we though?

It’s a magical mushroom chair you can place anywhere inside or outside your home. Weird? Definitely.

24. Royal Dogs

We’ve all met our fair share of crazy fur-parents.

Of course, the definition of “crazy” will differ greatly from person to person.

There are some fur-parents who dress their pets in ridiculous outfits no matter how hot it might be. Then there are crazy cat ladies who have more cat than house.

The Royal Dogs mod gives you the option to hang framed paintings of dogs dressed in royal armor. Either that, or it’s royal humans with dog heads.

Either way, there are four frames and seven paintings to mix and match, giving you a total of 28 combinations to choose from.

There’s a pack for royal cats as well, if that’s more your thing.

23. The Dungeon

When we think of The Sims, we usually imagine bright colors, happy cartoon people, beautiful houses, and organized neighborhoods.

Basically, everything is supposed to be bright, bubbly, and colorful.

Well modder littledica had a different vision of what The Sims should be: a darker, dingier vision than what we’re all used to.

The Dungeon pack includes different columns, arches, floors, and walls for you to use to be able to build your very own dark dungeon cave with.

22. Scars 4 Children

Character creation options in The Sims 4 already offer a lot.

But some players still find that options are lacking. This prompted Seyjin to create the Scars 4 Children mod.

While body scars were introduced in the Get Famous expansion pack, they were only available for adults.

Scars 4 Children make all of them available for children as well, for whatever reason you might need that.

Looking at some of the sample pictures – they basically make all the kids look like Chucky from Child’s Play.

21. Shark Fight

To expand on the Get Famous scar options even more, modder AlisterAzimuth created the Shark Fight Body Scar mod.

It’s not actually a scar, as he created a custom chest tattoo.

But the result is pretty convincing.

If you’ve ever wanted to give your sim an interesting back story, like say, that he had a near-death encounter with a shark before on some random beach trip… well you can do exactly that.

20. Urn Thermostat

This one is pretty self-explanatory, but let’s not judge a book by its cover.

The Urn Thermostat actually has a practical purpose.

Yes, it’s an urn that doubles as a thermostat. But an urn would otherwise not be placeable as a decoration!

So there you go, this mod lets you place an urn anywhere you choose. And it will double as a thermostat. Nothing strange here at all.

19. Grave Stone/Tomb Stone Sprinkler System

Here’s another one from Teknikah, the Tombstone Sprinkler System.

If you’ve ever wanted to decorate your house with a tombstone, well today’s your lucky day!

This mod lets you place tombstones anywhere you like. Keep in mind though, that its sprinkler functionality will only affect your entire house if it’s placed outside. For some reason.

18. Proposal or Marry NPC Ghost

We’re getting into pretty weird territory right about now.

If you’re one of those people that wants to decorate your house with urns and tombstones, it might not be to be too farfetched to assume you have a weird thing for death.

Well if your sim loved someone so deeply that they wanted to keep them forever, well keep reading.

With this mod by Simmiller, actions such as propose, elope, and marry will now be available for non-living sims.

I bet Casper wishes he could have gotten this in real life.

17. Snouts for Sims!

We talked a bit about character customization earlier, but didn’t get into anything too weird… yet.

Let me introduce Snouts for Sims!

You can now give your sims customized snouts, along with sliders for longer or shorter snouts, and integrated options for teeth to fit.

16. Rocco Superstar – Mixed Breed Dog

Speaking of animals, this mod lets you create a completely custom dog breed unlike anything you’ve ever seen.

It’s actually based on a Basenji, which is an actual dog breed. But it gets unique features that are just weird for my taste.

Rocco Superstar has purple and blue metallic skin, which looks almost rainbow-colored. Not only that, but he has actual rainbow-colored star marks all over his face as well.

15. SEGA Certified Hedgehogs

While we’re on the topic of pets, SEGA Certified Hedgehogs isn’t something you’re going to want to miss.

Modder woopa20 actually repainted hedgehogs in The Sims 4 to recreate the characters from the SEGA “Sonic the Hedgehog” series.

The hedgehogs come in grey, red, pink, and of course blue.

They come with customized habitats as well, you know to match their colors. And can be purchased for about 2k simoleons.

14. Juicaholic

We touched on the topic of traits a bit earlier, and this mod is probably the weirdest one I’ve seen on the topic.

As the Juicaholic in-game description reads, “This sim just can’t get enough of alcoholic drinks!”

Wait, you’re telling me this mod basically makes your sim an alcoholic?

The trait comes with a few buffs as well, where your sim gains +2 happiness while at the bar, +3 happiness after drinking, and will get tense if they don’t drink for 48 hours.

Things are getting a bit real here, folks…

13. Object Head: King Tiger

I’m not entirely sure what to say about this one.

The description doesn’t offer much insight as to what the purpose of it is, so I’m pretty much at a loss. Which is perfect for this list.

What it does is gives you the option to replace any sim’s head with a Tiger II tank head.

Yes, I’m talking about the Tiger II tank. The kind used by the military during wars. Yes, as a head for your sim.

12. For The Horde Career Path

There are tons of mods that expand on career options.

And while some mods add some of the real-world jobs that weren’t included in the base game, others are just plain weird.

Take this for example, allowing you to join the horde as a scout.

Based on the popular World of Warcraft games, you’ll be able to work your way up the ranks from a mere scout to become either a Warchief or a Champion of Azeroth. MMO lovers unite!

11. Pirate Career

If you feel scourging for food with orcs isn’t really for you, you can choose to explore the vast seas in search of hidden treasure instead.

Mod The Sims 4 Cc

This mod lets you become a pirate, starting off obeying orders on the ship as a sailor.

You’ll learn as you go and eventually become either a cook, cambusier, or surgeon through the Master path.

On the other hand, you could choose to go the Commandment route and grow into a Lieutenant, and eventually captain your own ship.

10. Ministry of Propaganda

Modders already include a disclaimer warning that this mod is strictly parody and satire, and is not to be taken seriously.

You’ll be starting at the bottom of a fake news corporation as a neighborhood speculator, with the goal of uncovering your neighbors’ deepest darkest secrets.

You’ll then have the option to choose between two branches – become a media personality, or engage in political leadership.

It’s certainly an odd one, but quite fun at that.

9. Flat Earth Movement T-Shirt

Moving along to the next conspiracy theory, how about this flat earth movement t-shirt?

Any takers?

Well unfortunately, the mod only provides a female-compatible version of the shirt. Sorry guys.

8. Teeth Genetic

Let’s go back to character customization for a bit.

We’ve been so preoccupied with giving our sims bigger butts, or transforming them into hairy mythical creatures – well how about something a bit more normal?

This pack gives you three additional teeth options to choose from. Now you can give your sims gap teeth, buck teeth, or snaggle-teeth.

Why would anyone want perfect pearly whites anyway?

7. Male Pregnancy Trait

I’m sure we’ve all heard it before.

The argument that it’s unfair how only women have to experience the struggle of pregnancy and child birth.

It’s been covered in movies and TV, but unfortunately it just hasn’t been made possible in real life.

Lucky for us, it’s possible in The Sims. All you have to do is install this mod and you’ll be good to go.

Not only can male sims get pregnant. But they’ll even develop breasts during their second trimester as a result of the hormonal shifts.

Neat, right?

6. Male Breastfeeding

Hold on a minute… did I write that pregnant males would grow breasts?

Well why not go the extra mile and let them nurture their newborns as well?

With this mod, your sim dads will be able to breastfeed their baby – provided that they gave birth to the baby themselves.

With these two mods you won’t even need a woman to mother your child anymore. Very progressive, might I add.

5. Gigantic Baby Costume

“They grow up so quickly.”

“Don’t you wish they’d just stay little forever?”

Those are some of the things you’d commonly hear from parents.

Thanks to modder bootsbrisket, your babies will never have to get old with the Gigantic Baby Costume mod for Sims 4!

Well technically, they’ll have to get old since the mod only works on adults… but they’ll still look like babies!

4. Cenotaph of the Tribal Covenant

It’s honestly getting harder and harder to explain these mods as I go along.

This one is different though, as it’s so unique that there’s so much to say.

It adds the Cenotaph of the Tribal Covenant as a decorative item which you can purchase for only $50.

Now here’s where it gets interesting. You can blow on the statue’s horn to call on Gunk the ogre.

Once Gunk has been summoned, he can do four things for you. You can either:

• Give him your baby
• Sell him your baby
• Take/buy a baby from his collection
• Challenge him to a fart contest

Convinced yet?

3. Deadly Toddlers

Earlier I mentioned scars that can make your children look like Chucky the evil doll from the Child’s Play films.

What if I said you could make your child actually act like Chucky?

Well with Deadly Toddlers, you can.

Deadly Toddlers adds a whole new pie menu of sadistic actions for toddlers, including stab neck, stab chest, and set on fire.

You can even set it so that toddlers autonomously kill other sims. Cute, right?

2. Extreme Violence

If crazy killer babies aren’t what you’re looking for, Extreme Violence might be just what you need.

Maybe you saw one too many crime documentaries and want to live out your crazy serial killer fantasy.

Well we’d all rather you did it in The Sims than in real life.

Mod The Sims 4 Mcc

Extreme Violence adds a Psychopathic Tendencies aspiration to the game, which will gain you the Horrifying Intimidation trait once achieved.

You can do some crazy things with this mod, including choking someone with a grilled cheese sandwich, or even causing a pregnant lady a miscarriage.

Granted there are some nicer aspiration mods to try out… but this one’s got to be the weirdest.

1. Honey, What’s Cooking?

Honey, What’s Cooking? is actually a nod to one of the older Sims mods known as OMGWTFBBQ.

This mod adds two new recipes to the game: Carne de baby and Carne de infante.

You can probably guess by now: this mod lets you cook babies and toddlers for meat.

If that’s not crazy, I don’t know what is.

We play EA’s Sims 4 to experience a detailed simulation of human life.

It’s fun to watch the wacky situations our sim counterparts get themselves into… or the situations we force onto them for our amusement.

But The Sims contrasts substantially with human life in its cartoonish nature. Everything is funny, absurd, and sims just take everything as lightly as possible. For them, life is simple.

Well not anymore! Thanks to the tireless work of some amazing modders, we can re-introduce some of the more nuanced aspects of human life into the game, increasing the simulation’s complexity and often making everything just a little bit darker, grittier… more real.

For anyone interested in making their Sims experience as real as it can be, here are the some awesome mods for increased realism.

20. Realistic Reactions

Have you ever been cheated on?

Hopefully not, but let me tell you it isn’t chill.

For this reason I always found it unrealistic that sims would just get angry at their cheating spouse for a little bit before returning to normal, at least whenever infidelity was actually discovered.

Creator Scaldwellhu agrees. And they made a mod to make cheating as big a deal as it usually is in real life.

Now couples will be devastated by the event, and it’ll take a lot of work to get things back in order. Even the kids will feel upset when their parents are in this situation!

19. Miscarriage Chance

Pregnancy is a beautiful process. But sometimes there are complications, and that’s just a fact of life.

This mod by LittleMsSam introduces a slight chance that one morning, a pregnant Sim may wake up with cramps and abdominal pain, prompting them to go to the hospital.

While sometimes they’ll come back with a healthy baby and make everyone in the household relieved, more often than not they’ll return with dark news despite the doctor’s best efforts.

It’s sad, it’s dark, and it’s incredibly realistic.

Now on the flip side, if you want pregnancy custom content that’s a bit more light-hearted take a peek at our pregnancy mods list. Not as much realism, but a whole lotta fun in there.

18. Pregnancy Overhaul Mod

Creator LittleMsSam doesn’t just want to put a damper on your reproductive fun.

She just strives for realism, which we can find in her Pregnancy Overhaul Mod.

Not only does it replace the absurd pregnant belly size found in vanilla for something more anatomically correct, but it removes the exaggerated pregnant walking animation as well.

It also lets expecting sims continue practicing yoga, swimming, and other such activities up to the beginning of their third trimester, as is normal for would-be-moms in real life(which I had to Google to confirm, I mean I’ve never been pregnant so…)

17. Risky Woohoo & Try For Baby Chances

Normally you can actively choose whether you want a sim to have safe Woohoo with a partner, or outright try for a baby and get them pregnant.

But that’s not quite how it works in real life.

Modder PolarBearSims came up with some tweaks to make the Woohoo experience more immersive by replacing it with Risky Woohoo, and implementing a complex fertility system affecting all sims.

Depending on their fertility levels, location of the encounter, and some other factors, some sims will have more of a chance of becoming pregnant accidentally than others. Sims may also become infertile, requiring them to get fertility treatments to actually get pregnant. If that isn’t real, I don’t know what is.

16. More Best Friends

I’ve never been able to give a definitive answer when someone asks who my best friend is.

I would never be able to pick just one. They’re all key parts of my life!

Thanks to creator LittleMsSam, your sims won’t have to pick just one either.

Now the “become best friends” interaction will have a 30-minute cooldown rather than a one-time use, allowing you to create inseparable squads of Sim besties.

15. SNB – Sim National Bank

The way money and bills work in The Sims 4 is pretty basic for a game made for simulating human life.

Sim National Bank by SimRealist is an in-depth mod that endeavors to overhaul the financial system in TS4, letting sims manage bank accounts, take out loans, pay their bills individually, and so on.

Quite honestly, this is one of the most realism-enhancing mods I’ve ever seen.

But only the most hardcore players will actually have fun introducing accounting into their sim lives, which is why I don’t place it higher in this ranking.

Mod The Sims 4 Hair Korean

But let it be known, this mod is exceptionally realistic.

14. Personality Please!

Sims are notoriously less complicated than humans. They take life one day at a time and often choose what feels right in the moment, rather than what makes sense in the long run.

Personality Please! by PolarBearSims is a mostly romance-centric rework that makes Sims considerably less promiscuous by making traits, aspirations, and past events greatly affect their relationships with other sims.

Now they’ll actually need to be compatible if you want them to get down and dirty.

Other than that, the mod also gives cats and dogs more varied personalities, and sims can learn traits and choose careers just from having deep conversations with others. How cool!

13. Automatic Beards

Ever since I turned 14 years old, my ever-growing beard has been an important part of my life.

Every morning I decide whether or not to shave, and the choice has important ramifications on how my life plays out. The same should be true of our digital friends.

This mod makes sim beards grow automatically over time, requiring constant shaving. Unless you want your sim to become Gandalf the Grey, that is.

12. SimDa Dating App

Dating and finding partners is astoundingly easy in Sims 4 compared to real life. Which is why we needed dating apps, and they don’t – until now.

The SimDa Dating App by LittleMsSam works a lot like a streamlined version of Tinder, allowing your sims to schedule meetings, set up blind dates, or simply call somebody over for a one night stand.

Each of these interactions has its own interesting features and possibilities.

You can start relationships, have some fun… and even get someone pregnant by accident. Just like real life!

11. The Explore Mod

Mod The Sims 4 Family Tree

While there’s a lot of places to visit and activities to enjoy in The Sims 4, there’s always room for some improvement.

And more autonomy is always good.

The Explore Mod by KawaiiStacie lets your Sims go out and explore the world autonomously, either alone or with friends.

They’ll have adventures, gain skills, meet people, and maybe even change their world view!

This mod adds several entertaining activities like gambling, getting your nails done, doing temporary work for an extra buck, and even going out to get takeout if you’re too lazy to cook. All very realistic and very immersive.

10. Height Slider

One of the most frustrating and unrealistic things in the game is how every sim is exactly the same height as others of the same age group.

Well thanks to this mod by creator Luumia, you’ll be able to give your sims different heights through a slider in CAS.

Everything else will, of course, scale proportionately to height.

As a bonus, Luumia included a hip shape slider and neck length variation for even more Sim variety.

9. Extreme Violence

The world is a very violent place, and even peaceful suburban areas like see their fair share of violence from time to time.

Extreme Violence by Sacrificial Mods adds the possibility for wrongdoing sims to attack others in a wide variety of ways.

Shooting them with machine guns, cracking their necks, chopping them up with a machete, and even crushing their skulls by sitting on them are only some examples.

I mean, I guess it’s realistic?

Not only does it add the acts in themselves, but a bunch of added functionality revolving around them, like the possibility for sims to acquire the Serial Killer trait, or paying a gang to off someone your Sim doesn’t like. Yikes!

8. Meaningful Stories

Sims don’t take life too seriously, and they’re incredibly fickle.

They may be completely devastated by the death of their pet one moment, then ecstatic because they watched a good movie the next with no in-between.

This mod by Roburky reworks the mood and emotion systems to make them more nuanced and realistic.

A depressed sim will need time and help from their friends to get out of a rut, and something like a first kiss will make them feel happy like never before.

Transitions between emotions also take time, and there are transitional periods when they’re feeling a bit of everything.

7. Passionate Romance

The romance system in vanilla TS4 is pretty basic.

You can flirt, go on dates, Woohoo and get married, but it never really feels like a relationship.

Passionate Romance by Sacrificial Mods improved this greatly by adding several new interactions like snuggling, hugging romantically, taking a romantic selfie, and even grabbing each other’s butts like they used to in TS2.

6. After School Activities

Going to school has never been just about learning history or science.

It’s also about making friends, acquiring skills, and finding yourself.

With this add-on by amazing creator KawaiiStacie you can add all these things. It endeavors to flesh-out educational experiences by adding over 30 after-school programs for children and teens.

Examples include the Anime Club, the Yoga Club, band, and basketball.

Mod The Sims 4

Sims partaking in these activities will learn skills, make friends, gain motives, and may even apply for scholarships depending on their performance throughout their school life.

5. Wicked Whims (NSFW)

If there’s something humans never get tired of, it’s sex. We love it, and so should our Sims if we’re to have a realistic experience in-game.

Wicked Whims goes a long way to develop everything sex-related in TS4, from turning the Woohoo interaction incredibly graphic to giving female Sims a fully-functional menstrual cycle complete with mood swings, cramps, varying fertility and a need for pads and tampons.

This one goes deep.

It even introduces contagious STDs! Now if that isn’t seriously realistic, I really don’t know what is.

4. Basemental Drugs

Alcohol and other drugs have been a reality of life since time immemorial, and that’s not about to change anytime soon.

Basemental Drugs endeavors to introduce this reality of human life into TS4. It lets your sim pals acquire, consume, and sell alcohol, tobacco, cannabis, and many other mind-altering substances.

Sims engaging in these activities may become addicted, have problems with the law, get arrested, and even go to rehab… and that’s only the tip of the iceberg.

It’s not pretty, but it is the real world.

3. Basemental Gangs

If you like Basemental Drugs, the Basemental Gangs expansion is sure to pique your interest.

It fleshes out the entire drug dealing aspect of the mod, allowing you to create a criminal empire and become the leader of one of four gangs.

Again, dark but quite brutally realistic.

You’ll have underlings, earn loads of blood money, and there’s even an entire skill system to become a better thug. It may not be wholesome, but it sure as hell is realistic.

If you’ve ever wanted a little more GTA in your Sims experience, this mod is the ultimate crossover.

2. Life’s Tragedies

As you may have realized by now, not everything is glitter and candy.

There are tragic and difficult moments in everyone’s lives. And they can arrive when you least expect them.

Life’s Tragedies by Sacrificial Mods adds a wide variety of possible tragedies that may befall your Sim or NPCs close to them. Like randomly being run over by a car, getting jumped by a homicidal maniac, or even contracting a life-threatening disease they’ll need surgery to overcome.

It may seem a bit intense, but don’t worry. You can control how often these tragedies happen, so you can either turn your Sim’s life into a horror story or just inject a tiny bit of dark realism into your game.

This will be absolutely hilarious, devastatingly upsetting, or some kind of in-between, depending what you’re looking for.

Just note the download page includes a lot of other mods from this creator, so look towards the lower part of the screen for their “Life’s Tragedies” download file. It does get updated from time-to-time so if you want the absolute newest version definitely grab it from the link above.

1. Slice of Life

Easily the most comprehensive and complete realism overhaul for The Sims 4 is Slice of Life by KawaiiStacie.

It’s an extensive mod that touches almost every aspect of life in the game.

Your sims get visible emotions, recurring memories of past events that’ll affect their moods, a complex fitness system, and reactions to their own appearance. Among many other things!

One of the most impressive features of the mod is giving every single sim a personality based on the Myers-Briggs 16 personalities test, which affects the way they behave and interact with other sims to a great extent.

It also adds many features we’ve already seen in previous mods such as functional alcohol, serious sickness, and a complex menstrual cycle, all in a single polished CC pack affecting every sim in your world, including NPCs.

This is truly the ultimate realism mod for The Sims 4, hands down.

If you need a one-stop shop realism mod then give this a try before anything else. You’ll be surprised how much it offers.
