@endimos we're talking PLATFORM exclusive. theres a big difference. LBP and Modnation are SONY exclusive. Mario is Ninty exclusive. is NSMB DS exclusive?? yes its a different game than the one for Wii. same goes for LBP different games same series. Is ME2 360 exclusive??? no its not, I can get it for my PC and its the same damn game. As for why MS wouldnt put games on PC also, simple they want people to buy 360, most people have a PC already. Last time I checked MS didnt make PCs either so they dont get all that bread. why would you buy a 360 when the "exclusives" could be bought on something you already own. its not a coincidence that Halo, Alan Wake, and GOW2 were 360 exclusive, they saw the need to have actual exclusive content like the other 2
