Those are the ones I could think of off the top of my head and all of them I’ve gone back to do complete them on different levels to get the maximum 1000 gamerpoints (yes sad I know lol) like completing GOW on easy, hardcore and insane. I’ve also clocked a lot of those arcade games.
I'm about 3/4 way through Spinter Cell Double Agent and GRAW 2 but I got the dreaded red rings of death over the weekend.
