Which Sims 2 game should i buy for P.C.?
Personally I think that Seasons is the best Sims expansion I have played. The only expansion I don't have is Bon Voyage and I'm hoping to get it soon. But Seasons is so much fun. They added all sorts of new activities and the weather system is great. I'm constantly finding new things with that expansion. And all my sims love to fish =) Sounds boring but the food you make raises your energy like crazy. Gardening is great too because with the juicer you can make juices that have different effects. Plus building snowmen, seeing the penguin, plant sims are all fun =)
Reply:well first u need to get the original sims 2 bc the other ones are extension packs and i would say the best extension pack is pets that seems pretty fun but there all fun. so pick which one u want.
Reply:I would go with seasons.And even BonVoyage.
Reply:Ok first, first don't get pets it is really annoying you can't do anything without the pets annoying you. Seasons and university are really good .
