OMG some people know nothing of what is programming they are doing it on a PC as all games and then they start using dev kits wich are kind of pcs with hardware similar to the ones on the console and port the code and optimize it.
I remembered that there was a GOW when it was beeing developed only for 360 and they wherer working on a pc?? does that make GOW a PC port?? NO... working on a pc doesnt mean its done to work on a pc like a game for it
