Hmm, not my view but good to see we all have our own ideas.
My views: Dead Island was good for a while but got stupidly repetitive and one dimensional after a while.
Crysis 2 was very very good although nothing exceptional.
Portal 2: Dunno, yet, I may grow to like this, but it's not as clever as it thinks it is.
Battlefield 3 (single player) just another fps with amazing graphics and standard gameplay, short, shoot-em-up by numbers, basically.
Witcher 2: I have this, had a brief dabble, looks good but as I'm still playing Witcher I gonna wait til I finished that one. And I think Witcher 1 is excellent (the reissued enhanced edition, original release was rubbish).
