EDIT: When talking of suggestions, it should be noted I'm looking for local co-op, not online co-op. Not sure how many games of those you mentioned allow for splitscreen.
EDIT: Ah, GoW2 has splitscreen allowance, neat.

Maybe I'll get that sometime. Not too bothered about the online multiplayer - the only people I know online that I played with regularly were Dan and Psy, and after a lot of initial awesomeness in Halo 3, in the end they must have had enough of my inadequate skills and spent most of their time killing me for giggles. I got bored of that after a while.
