The games I've played enough of to actually give a decent opinion on (ie, not trials or just a couple of levels/chapters)...

Football Manager 2011 - 9/10 - Nine points because THIS GAME IS CRACK. Didn't get the last point because THIS GAME IS CRACK.
Mass Effect 2 - 9/10 - This game was awesome but didn't feel even close to long enough.
Final Fantasy XIII - 8/10 - Gameplay lacked a bit but characters were one of the best sets ever for me. Really enjoyed the whole thing regardless of whatever criticism was thrown at it, so that's enough for me.
Final Fantasy XIV - 6-7/10 - So... much... potential... I can't wait for this game to get decent content because everything else is right there. And it's improving steadily from the lacking game it started out as. 6 and 7 out of 10 purely on the basis that it's (obviously) changed a lot since release.
Army of Two: The 40th Day - 8/10 - It's like playing an 90's average-budget action movie. I love this. Although I don't know if it'd be as good if I didn't have Danielle playing with me.

2010 games I haven't played enough of to give a decent opinion yet: Lost Planet 2, Lara Croft and the Guardian of Light.
Non 2010 games I played for the first time this year: Resident Evil 5, Hamster Ball, Uncharted, Uncharted 2 and probably a bunch of others.
