The sims 2 for pc

Which Sims 2 game should I buy for pc? I love the game, but I just can't decide.

Thanks!

hmmm... I love all of them, so I got the 'Sims Complete Collection' it was like #32, but all in one game is unleashed, hot date, livin large, house party, vacation, superstar, and the sims makin magic. its so fun! if you dont want all of them, the nget sims pets. its regular sims but with animals.

um you probably should get the sims 2 seasons or freetime or nightlife...but freetime is really fun and you get to do awesome stuff
