It's easier to just call it an expansion, since most people would understand that even if they're not a simmer. Right now I just have sims3, I have collecters edition :) I'm starting to get a little bored with it so I'm thinking that once I have enough money I'll pick up ambitions. If you do pick up the sims3 so you can play it tell me how it is, I'm not really in the mood for looking up random pople from gamestop's opinions on the game so it would be neat to see how forum members like it.
