And we can safely say that we have tried most of the Sims 4 trait mods that exist in 2021. So, here we’ve compiled the best choices that we have ever played with.

So, trait mods are deeply personal. You want to get the ones you really want to use, or the ones that are similar to your real-life personality. That way you can have an awesome experience.

Eternal Youth” And “Immortal”: Buyable Sims 4 Traits Mod

Who wants to live forever? Now you can cross the aging problem off of your list and enjoy the unending pleasantries of life. You can experience every expansion pack and live through every possible storyline that you can imagine. Your Sim can stay young and unable to die, as long as you follow the rules.

As you can see, you get two traits in this pack. And there is a great difference between them. The first one, Eternal Youth, only eliminates death by time. The Grim Reaper will be more than happy to visit you if you injure yourself a lot, so remember that. 

On the other hand, the Immortal trait will give you complete immunity from the Grim Reaper. This means that he won’t be able to collect your soul. However, Immortal doesn’t stop the aging process, so you’ll continue to age but not be able to die of other causes.

Unlocked Lot Traits

Unlocked lot traits? Yeah, you read that right! Here are the ten characteristics for your home at your disposal right from the get-go!

Okay, so, many simmers have a problem with not being able to use all the lot traits from the beginning. This means that they have to live in a house first, and slowly unlock the traits that make their ideal home. And this is a big no-no!

However, the “Unlocked Lot Traits” mod removes that limitation altogether. Now you can make your home in any combination of traits, for example, Sunny Aspect, Party Place, and Penny Pixies!

Woohoo Lover

By now we have covered all types of traits, but the Woohoo lover is a special one. Its name can tell you everything – this is a trait for a Sim that likes to Woohoo with everyone! But the trait is also great for spouses and Sims in relationships.

The Woohoo lover trait simply boosts your Sims’ want to have woohoo time. As a result, these Sims are more flirty and they will spend more time trying to look “presentable”. Additionally, they will engage in Woohoo or at least romantic kissing way more often than before.

Second, their singing, charisma, and mischief skills are gained 1.5x faster. And third, siren Sims are exceptionally good at love affairs and relationships!

Pyromaniac Trait

And the last trait that we want to showcase here is the pyromaniac trait. We admit this isn’t among the most popular nor the most impactful trait mods for The Sims 4. However, playing the game with a pyromaniac Sim is one hell of a blast (pun intended)!

Sims with this trait are able to create fires easily. They have a natural affinity for combustions, so they can set things ablaze all the time. But, pyromaniac Sims are also immune to fire! This makes them a constant threat to everyone around them, except themselves!

You can download this mod here. The official publication was made on ModTheSims by nl_alexxx.

Insomnia Trait Mod

Contrary to popular belief, insomnia is a serious medical condition that many people suffer from. But, we haven’t seen or heard anything similar to it in The Sims 4. Until the Insomnia trait mod, of course!

This Sims 4 trait mod is an excellent way to introduce a highly realistic condition to the game. If you aren’t familiar, the insomnia trait will make your Sim unable to fall asleep. As a result, they will need to spend the nights awake and engaged in some sort of activity.

Prepare to accompany your Sim through the night as they struggle to keep their needs up and not be miserable. The mod gives you a 1.25x faster skill gained, so you can use that to your advantage.

There is a lot more to learn about his trait, so we suggest you read all the info at this site. There you can also download it follow its wonderful creator Didelphimorphia.

Isn’t it better to hide in your own corner of the world and live your life exactly the way you wanted? Yes, right, so head over to ModTheSims to check this trait out or follow this link for a quick download.

Honestly, there are great benefits that come with this mod. For example, introverted Sims are able to learn skills faster. On top of that, their social need and fun meters decay much slower. But, the bad side is that these Sims are also worse at relationships. So you’re going to have to put in a bit of extra work to make a relationship work!

Alcoholic Sims 4 Trait Mod

From TheSimsCatalog we have this awesome Alcoholic trait mod. What’s great about this trait is that it converts our Sims into regular old alcohol maniacs. It makes them want to during the day and the night, drowning their problems in sweet liquor.

In all seriousness, “Alcoholic” is one of the best Sims 4 trait mods on the internet. It’s simply fantastic that we can see alcoholism in the game and take proper care of the Sims that do have it. It makes the game more realistic and fun to play, so we highly recommend you try it out.

The creator of this trait is TheGraveThief and you can download his mod here!

New Hobby Traits

Hobbies take a lot of our time. They also shape the way we view or think of things, so we consider them very important in The Sims 4. That’s why we’re wholeheartedly recommending you the “New Hobby Traits” mod from kutto. It’s available for download on this page of ModTheSims!

In short, here you will find 8 hobbies completely new to The Sims 4. They are Artisan, Competitive, Horticulturist, Movie Buff, Scribe, Technophobe, Worldy, and Thinker. And each of them is unique in its own way. For example, Artisan Sims are happy when they build things, while Movie Buff Sims just love to sit around and watch movies.

All these hobbies are highly realistic and they play out nicely in-game. That’s why “New Hobby Traits” is one of our favorite Sims 4 trait mods!

Feminine and Manly Traits

On the topic of gender, we have to admit that Sims sometimes don’t act traditionally in the game. In other words, a female Sim will often act like a man, regardless of which traits, aspirations, or goals you have chosen for her. And the same goes for male ones.

Well, the best way to solve that problem is by adding the “Feminine and Manly Traits” mod. This extension will bring your Sims to life and give them more depth of character. You can choose a feminine trait for your female Sims, as well as a manly trait for your male Sims. This will highlight their gender and make them more recognizable.

However, keep in mind that this mod will also turn your Sims into the two stereotypes of a man and a woman. But both of these traits have their own unique bonuses, so we highly suggest you to give them a shot!

New Emotional Traits

When it comes to emotions, The Sims 4 can also sometimes seem too immature. Sure, we have our Sims have the most basic emotional responses, but that’s all of it. However, in the case of the “New Emotional Traits” mod, you’re looking at a completely different thing!

What do you get with this bundle pack?  Well, you get 9 new traits, each of which represents an emotional aspect. So we have Calm, Insecure, Oblivious, Restless, Stoic, Arrogant, Daydreamer, Perky, and Egghead. And you probably know how all of them can make your Sim act.

Two-Faced Trait

“Two-Faced Trait” is one of the most interesting Sims 4 trait mods to play around with! Yes, this trait will make your Sim an unworthy and lying individual that always gets his way. Sims with this trait are able to learn mental skills faster, as well as be overall better in social situations. And this makes them the perfect villains!

Additionally, skills like charisma and mischief will be gained significantly faster. So you will be able to lie and cheat your way to success.

Boyfriend, or girlfriend material Sims are more knowledgeable about how to make their partners happy. They are more agreeable, talkative, and willing to endure the hard times together. As a bonus, they build up skills faster, they have more fun with the opposite sex, and their hygiene decays slower. Additionally, their relationships increase 15% faster and decay 10% slower!

Yes, the “Depressed Trait” mod is another highly realistic trait mod that you must try. It’s created by saphryn and you can download it from here. 

Now, there are a couple of different moodlets that you will receive with this mod. For example, “Feeling Depressed” has a 65% chance of triggering and is characterized by sadness.

Sims 4 Autism Trait Mod

Next on the list is autism. We have chosen this mod created by Lindsay and published at TheSimsCatalog. As in the real world, Sims with the Autism trait will struggle with their social skills and will get often uncomfortable in social situations. They will only talk about certain topics and won’t engage in anything that they aren’t comfortable with.

ADHD Trait 2.0

The ADHD condition should also be familiar to everyone. It is one of those character traits that can be very prevalent in the real world, yet it is still missing in The Sims 4. So, we have found this brilliant mod, done by o0ohaleyo0o and published originally at ModTheSims. 

It’s enough to only know that ADHD will appear in every aspect of your Sim’s life if you choose to play with this trait. So, needs, skills, careers, and even homework will be affected by the condition. Your creativity skill will skyrocket, as well as your affinity to be mischievous.

We can guarantee that this mod is the complete experience of ADHD in The Sims 4! Head over to this page to read more and make a download!

Shyness Trait

Unlike the more serious conditions, shyness affects everybody to some degree. And while that’s true for the real world, it is less so in The Sims 4. We have found that Sims don’t get shy too often and aren’t really embarrassed by their actions. And this is ridiculous because it is not realistic at all.

Well, the “Shyness Trait” mod by the popular MissBee changes all of that. It adds a proper trait that makes our Sims generally shy. With it, they will have a hard time expressing themselves, being comfortable, or under pressure. Instead, these Sims will only be happy with their close friends.

To try out this mod, follow this direct link.

Trait mod - Shyness

Gamer Trait

With every year, the “gamer” profession rises to popularity. For many, video games are the future of our world. We play The Sims 4, so that makes us gamers as well. And what do gamers do? Well, they play video games, of course!

The gamer trait in The Sims 4 gives a natural video game affinity to our Sims. They will often want to pursue careers as gamers and compete with other gamers as well. However, Sims with this trait are also excellent hackers and programmers. They only want to spend time in front of a computer and they consider social gathering a chore. So, are you in?

It will just add a natural tendency to create worlds, seek answers, and imagine things! Sims with this trait are often daydreamers, prone to getting a surge of inspiration at the moment!

Truthfully, this trait does not impact the gameplay in any major way. Instead, it is just an additional flavor that enriches the writer career path, before it is even chosen. We’ve had a lot of fun with it, so we recommend it to you as well. You can find more about the “Author Trait” mod on this page
