Mass Effect 3! Loved it right Until the end... Then raged at the end lol. Didn't realize that to raise your "Galactic Readiness Rating" you need to play the multiplayer, dunno if that changes the end at all tho.
Tried SW:TOR and got bored... I used to play EVE Online a fair bit but again, got bored with it.
I am looking forward to Dust 514 on the PS3 when it eventually comes out, it's a planet based warfare MMO that will tie in with EVE: corporations can hire your mercenary group to try and capture territory for them from other players.
I've got Forza4 and Fallout 3 on 360 on the way from the UK (no way I'm paying Australian retail prices!)
