Ever think of what traits your favorite characters would have?
Even if I don't plan on making sims for them, I often go through what traits characters I like would have. Like...just to pull an example out of the air, Parker from Leverage would have Kleptomaniac, Daredevil, Inappropiate, Childish, and possibly Loner. Giovanni from Pokémon would have Ambitious, Cat Lover, Snob, Hates Children, and maybe Workaholic (I did make a sim of him and I forgot what traits I gave him hahaha).
