What do you play as in TS4

I have myself and hubby in the game but don't play as them (enjoy seeing them in the world). I tend to make a variety of sims based on ideas that I have, but also include some from my favorite shows, games etc. For example, the Witcher cast/family is in Windenburg on the isolated island with a few other families I've made. When supernatural came out I downloaded the Mystery Inc Scooby Doo gang to solve all the ghost cases.
