The Walking Dead - still one of the best gaming experiences I've ever had, and like KC said, certainly the most emotional involvement I've ever had in a video game. Definitely a top 3 all-time game for me

Mass Effect 3 - played like the first half hour of this, got bored. I think part of it was I had just stopped playing New Vegas (which I probably put 150+ hours in) so I was kinda burnt out on RPGs. Plus the setting honestly bored me. Probably didn't help that I didn't play the first two games either! (:

Dishonored - very fun game. I usually hate stealth games so the fact that I liked this so much says a lot. Although the way I played could only loosely be described as stealth I suppose (: There were only a few missions that didn't turn into bloodbaths for me. I think that's part of why I liked it though (and didn't get frustrated), the fact that they give you the choice of how you want to complete the level and don't penalize you either way

Assassin's Creed III - played it for a while at a friend's once, eh. Never been a huge fan of the AC games. They're fun for a little while but get stale pretty quickly
