ahem 360 hasnt been relevent for about 3 years. Sony innovates with mature games like Heavy Rain, Beyond, The Last Of Us. Xbox just uses rehashes of Gears, Halo, Fable which are the epitemy of games for nerds and idiots who play games for "gunz and blood". Sony is always pushing for this entertainment sector to become more adult and not looked down upon as a geeks hobby. Microsoft are completely the opposite.
for me I remember being disapointed with resistances graphics. maybe because I'd already made the leap with 360 but it just seemed bland and nothing special. Killzone looks great though
