All righty then, let's update my list:
Transformers: War for Cybertron and
Transformers: Fall of Cybertron Such a great, and what it seems, slightly underrated game series. There is some great action to be had in both games, combined with neat dialogues and known Transformers characters. Top visuals. Story that gets you going, but nothing too fancy. Finished both games on hardest difficulty level (it wasn't that hard, though, there where some battles that I can consider a pain in the behind). Overall, I'm not a Transformers fan in any way shape or form, and yet I've enjoyed those two games very much.
Papers, Please Such a great game it is. Played this one way too much latley and, let's say, gotten through a couple of scenarios already. I really liked the visual style, setting, atmosphere, sound assets and the story that is going on. Do yourself a favor and try this one out.
Dead Island: Riptide As for my coop adventures, I've played this one all the way through with my brother. A neat game and a huge timesink. We had a lot of fun slashing zombies into small pieces and beating them into jelly. It's really hard to stop playing once you get into it :D
We had finished all of the main story and a lot of sidequest for a 100% story completion and got most of the collectibles out of the way (I believe it's 10 left), though, we're probably not returning for a full challenges and achievements completion (we're at 55%-60% completion when it comes to this stuff).
King of Dragon Pass Finally gone trough a campaign properly. And I'm definitely returning for a harder playthrough. But for now, all hail clan Whoopsie.
Also, I've stoped playing Skyrim and Daggerfall. Almost finished GRID 2 and I'm continuing my adventures in Dark Souls: Prepare to Die Edition. I've also started Trials Evolution latley and right now, I'm mid-way through completing the singleplayed portion of the game.
Rest of the games I've finished in 2013, for a full list you can visit:
