Top 10 of 2010
My best of 2010 so far based on playing 35 games so far this year and completing 25 titles. (updated 10/13/10) Halo Reach and God of War 3 both just miss the final spots on this list. I enjoyed both of these games, but in both cases they felt simply like uninspired graphical upgrades to older, better games. Maybe I'm just tired of the gameplay formula in both which neither of these games really advance.
Also notably missing are Mass effect 2 and Starcraft 2, neither of which I've played. With the former, I'm holding off until I can bring myself to slog through the original first. The second I haven't been able to play because it won't run on my hardware and as my interest is only in the single player, I'm not going to rush to upgrade in order to play it.
