I will shamefully admit that I did very little PC gaming in 2013, just some TF2, CS:GO, and failure at trying to play DotA2, really. I got a little Dishonored in before the end of the year, and some Half-Life, but I don't think that I finished any PC games in 2013.
On the console side, I played a lot, but didn't necessarily finish a lot. I re-played the Black Ops campaign (the first), to get some Achievements. I did the Halo 4 campaign a couple of times, I think. I beat Ghost Recon: Advanced Warfighter (again, the first) on Hard, but I put the invincibility cheat on because I wanted to just get through it, after the game cheated me out of Achievements for the campaign years ago. I beat the Forza 4 campaign. I finished most (if not all) of my Achievements on NBA 2K10. My cousin and I co-op completed the first Borderlands (working on the second, again in co-op), though we've got to go through again to finish getting to level 50 (and maybe get a used copy of the GotY edition for the sake of playing the DLC). Oh, and I finished up some Achievements (got 1000/1000 now) on Assassin's Creed II.
So little bit of PC, but a lot of console, as it's always been. However, 2014 looks to be different. I got a Humble Bundle and 10 Steam Holiday Sale games at the end of 2013, so I have about 40 games in my library to play. With just 5-10 360 games to complete, and no Xbox One, 2014 is looking like the year I get into PC gaming quite a bit (and it had better be, given the money I'm going to be putting into my PC).
