Reasonable on 27 August 2008
Guess what, everyone's going to have a list based on what they like. If they're smart, they'll buy the console / PC that suits it (or combinations thereof).
For me as I tend to play shooters on PC the 360 catalogue doesn't have half the draw as it would to others. The PS3 catalogue is a little better with titles like R&C and GT, etc. but is still pretty anemic as there seems to be an overfocus (from my point of view) on competing with shooters on 360. Wii has some games that appeal to me but many do not.
I have a PC / PS3 / Wii which just about gives me what I need - but right now I'd say no platform really calls out to me with a massive list of titles that dwarfs the others.
Try to be reasonable... its easier than you think...
