Wii. The XBox 360's graphics (forgive me old buddies who knew that I loved high-graphic games) look TOO good to me, and most 360 games are extremely bloody FPS's... It didn't bother me before, but with next-gen graphics it's really disgusting.
The PS3 doesn't really have anything I want. Nintendo does a good job of keeping the graphics good, but not too good - and obviously with Metroid, they don't over-do the violence. FPS's don't have to have blood everywhere for it to be realistic; and who would want games that look 100% real?
My bro has a 360 I can, quote on quote, "play whenever I want, as long as I ask." And I have a Wii, but my mom is being stubborn and not buying a single game, and right now I have no money....So....Yeah.
