I enjoy Sims, but usually only for short periods of time. I'll get in the mood to play it, and start a new character and house and everything, then after a certain point I kinda get bored of that one and either stop playing for a while again or start a whole new house.
But at least in Sims 2 you can die of old age. Though chances are by that point you've gotten married and have kids to play as. I once played through three generations.
