I played GoW 1 & 2 In quick succession and both through my PS3, in all honesty the ps3 doesnt do anything to it but i was playing it on a 42" HD Tv and there was definatly a huge difference in not necessarily in the quality of the graphics but squeezing more power out of what they've already got, you do notice that the Environments in GoW 2 are a lot more detailed and the frame rate is a lot more stable along with it :) The only thing the PS3 Noticeably did was eradicate any kinda of loading time :P
