Sims 4 Character & Storyline Builder FAQ

A web app that helps you plan your Sims 4 households before diving into Create a Sim (CAS). Select which expansion and game packs you own, choose household size and pets, then randomize or customize aspirations, traits, likes, dislikes, and styles for each Sim. All content is filtered to match your pack selection—no mods required.

You select the expansion and game packs you own. Aspirations, traits, likes, and dislikes are then filtered to only show content from your selected packs. Base game is always included.

You can create 1–8 Sims, plus optional pets (cats, dogs, horses). Total sims plus pets cannot exceed 8. Cats and dogs require the Cats & Dogs pack; horses require Horse Ranch.

Infant, Toddler, Child, Teen, Young Adult, Adult, and Elder. Baby is not included because it's not available in Create a Sim—babies are only in the bassinet in-game.

Yes. You can choose to include or exclude occult content (Vampire, Werewolf, Spellcaster, Fairy). Aspirations and traits marked as occult will only appear when you allow occult sims.

No mods required. This is a standalone web tool. You build your household here, then recreate it in The Sims 4.

For each category (life stages, names, aspirations, traits, likes, styles, glasses), you pick one: Randomize = we generate it and show it in the results. I'll Choose In Game = you'll pick it yourself in Create a Sim; we won't show it here, so you have freedom to decide when you're in CAS.

The app enforces in-game rules: if your household has any minor (Infant, Toddler, Child, or Teen), you need at least one Young Adult or Adult. Minors can't live alone, so the generator ensures a valid household.

Children get 1 trait; teens and older get 3 traits. Toddlers get 1 toddler-specific trait. Infants get no traits. Pets (cats, dogs, horses) can have up to 3 traits each when you select them.

Toddlers and infants don't have likes or dislikes in Create a Sim, so the app skips them. Children have a restricted set of likes. Teens and older can have full likes and dislikes.

After you generate, the app shows a short storyline summary (household size, who's in it, life stages). It helps you remember your plan when you recreate the household in The Sims 4.

Yes. Base game is always included. Select only the expansion and game packs you own—the app will only offer aspirations, traits, and likes from your selection.
