Yeah, but the Wii only has like four games for hardcore gamers... :\ On the 360, you have CoD4, Mass Effect, Gears Of War, Halo 3, Halo Wars, Half-Life 2, etc. Thats the thing I really don't like about the Wii, not enough games for the hardcore games.
Uber late reply FTW!
Anyway. I'd consider myself to be quite a gamer (reason I'm spending 600 EUR on a Graphic Card). So I'll have a PC for the 'hardcore' games and my Wii for fun. IMO there would be no sense in having a high end gaming PC and also get a 360 or ps3 that basically just does the same thing (but not as good (exception for XBL though))
