Trying to think back to order I played shit, obviously not all games from this year specifically...
Metal Gear Rising + DLC (PC), Jazz Punk, Bioshock Infinite, Demon's Souls, Far Cry 3: Blood Dragon, F.E.A.R. 2: Project Origin, Dishonored, NieR, Yakuza, Drakengard 3, Shadow Tower Abyss, Devil May Cry 1, Shin Megami Tensei IV, Vampire: the Masquerade - Bloodlines, Deus Ex Human Revolution - Director's Cut, Dynasty Warriors 8 Xtreme Legends, Another Century's Episode 2, Hyrule Warriors (Campaign, not Adventure mode), Alien Isolation, Bayonetta, Bayonetta 2, and just recently Resident Evil Director's Cut.
Yeah...that's a lot. And a good portion of those were during the summer when I had more free time.
