Well soriku.. I think he is right about the ps3 having better games but I dont think it has no games..
As far as exclusive games go, the PS3's line-up is an embarrasment with only a couple of exclusive games actually worth owning; most of their best games are also available for the XBox 360, and have often been available for 6 months or more before being released for the PS3.
When you include multiplatform games the PS3 has an edge, but most of the multiplatform games clump in a small number of genres (racing games, FPS, and sports games) so it is only better if you're a big fan of those games.
The Wii has a far better line-up of exclusive games, and has many game styles which are completely unavailable on other platforms.
