Seeing as Halo 3 and Killzone 2 are on different consoles, I don't think they can really directly compete with each other in the way many people seem to do.
Now, did you really mean Gamestop? Or could you have ment Gamespot? If you really did mean Gamestop, then it's pointless to really look into it as the gamestop preview/review sections for their games usually becomes a crapping fest for some people.
