Do you re play the same household?

I have some Sims I've made who I really love, and I've been known to set them down in a new world with a makeover and give them different stories. It's like an Alternate Universe; it's pretty much the same character, but in different circumstances. Some of them I change very little from game to game. Phoenix Valentine, for example *fans self* has been a ladies' man since Sims 3. Whether he uses his powers of hotness to become a rock star or a cult leader is up for grabs, but he's using his charm either way.
