The 2011 PlayStation 3 version of Mass Effect 2 is superior to the 2010 Xbox 360 in many ways, but not in the way of the printed instruction manual.
Witness the further decline of the tree-slaughtering gaming manual and/or its digital rebirth.
Personal note: I played the Xbox 360 version of Mass Effect 2 and never once needed to page through its printed instruction manual. I doubt I'd use the PS3's digital one either. Neither is impressive.
