Why the 100 Base Game Traits Pack is fun: This mod is a must-have for those of you who are bored of the same old traits, which is everyone at this point. There are 5 separate parts to the bundle and all traits are base game compatible so you don’t need a heap of the expansions for it all to work properly. They have such a wide range of traits so that you can make your sims truly unique from one another. They have various trait bundles, which I’ll showcase later on. This list will count down the 10 best trait mods for the Sims 4. Luckily for us, we have modders! There are a ton of custom traits available for download, so it’s easy to search and find anything specific that you want. Sure, you get a few new traits with each expansion pack, but they’re not very fun even then. Traits in the Sims 4 are severely lacking any sort of originality.
