Some interesting choices (even more-so for me as I have only actually played on about 3 of the games!).
Red Dead Redemption made it in at #1. Best game of 2010!? I'm not sure if I would call it that.
Glad to see that one of the Mario games for the Wii, it was Super Mario Galaxy 2, made it into the top 10. They may not pack the oomph of some of the bigger games eg Black Ops, but for entertainment and enjoyability I think they are right up there. I think I actually prefer New Super Mario Brothers, but that came out in 2009 so cant be counted
Some "Honourable Mentions" that didnt make the top 10 are Fallout: New Vegas and Alan Wake.
