Dark Souls II
Tropico 4
Far Cry Blood Dragon...
I have to say, I've finished Dark Souls 1 this year and am enjoying Dark Souls 2 tremendously. They are games that appeal a lot to me, not because of their so-called challenging aspects (which are vastly overrated I think, unless dying automatically means challenging), but because of the their low-ish fantasy setting that brings me back to an older and darker style of fantasy, and because everything in the game is meaningful, every item is unique, etc. It feels like it has a thick, rich texture. I don't know how else to put it. Some aura of myth. Some deep lore which isn't exposed to you by long-winded characters and cut scenes as if you were a 4 years old. It also reminds me a bit of games like Castlevania Symphony of the Night, or Metroid for SNES, which are a game style that I enjoy. But Dark Souls games aren't strictly "Metroidvania" that's for sure.
Probably requires a controller, and I find the game strangely satisfying to control with my xbox360 controller that I bought for my computer. So yeah, I've had a kind of Dark Souls obsession this year, and these games probably sit rather "snuggly" in my top 20 games of all time list (that was a pun for other Dark Souls players out there, wherever you may be, although I seem to know basically no one who owns Dark Souls 2 on my Steam list). Maybe even in the top 10 who knows.
