Starcraft II (PC)
Civilization V (PC)
Fallout New Vegas (PC)
Valkyria Chronicles 2 (PSP)
Fable III (X360)
Halo Reach (X360)
Probably a lot more though as I don't remember all the games that are releasing this year and there are some without release date. I also maybe buy Wii this year so that would also add couple of games to the list.
