Weird, even on TV this week there was a guy saying the sims was like playing dolls! I've never played the game so i can't juge but it's odd that this comparaison is often made. In a way i can see why, you don't exacly make yur lego characters go to work, date, have kids and all that stuff. Even Action figures are usualy not used for that kind of gameplay unless your little sister kidnaps GI Joe and forces him to marry Barbie!!!
I used to take the legos to build a forteress to protect My Joe's from the Pink Vette during drive by LOL. Then again that was over 20 years ago maybe nowdays boys play differently.
Anyways I hope the sims keeps selling well, maybe someday we will see some of their AI developements get used in other game types.
