Ah, yes, the biggest middle finger to PC gaming in 2009 is also the best game. Not surprised.
I have not played any game on the list, although I have Mirror's Edge, and I'm not much interested in the rest, save for ARMA II and Machinarium, though I would have to play some of them to be really sure. I would definitely mention Trine as one of the best games released this year, even though I have only played the demo :D
I know of one game that's coming out on Dec 26th that is high on my radar of games to check out.
