Online: BF3 mostly,.. tried MOH 2010 and crysis 2 after humble deals (decided BF3 is still No1.)
Co-op: Dead Island - opened world, good atmosphere and fun co-op future.
Single player: XCOM bureau Declassified - love it so far, good 60's atmosphere, gameplay reminds me bit of MASS EFFECT- 3 person in team, give orders and use abilities of all 3, dialogues with various answers, combat too similar too.
