I own the 360/ps3/wii, however I only use the 360.
No good games for the wii really (besides the ones I already beat, such as the amazing paper mario), though I do play some classic games on my wii, such as super mario world, and donkey kong country.
same deal with the ps3, it gets a workout as a blu-ray player.
my 360, i play whenever I get the chance.
I still use my pc for most gaming needs, except when rendering, then I have to use the 360 =P
