Well I just bought Darksiders II along with three DLCs for it, and also bought the Season Pass for Borderlands 2 which should help convince myself to complete my second playthrough. Well, I had the intention to complete it anyway at some point, but the new content will make that second playthrough feel new again to some degree. I just haven't touched the game in a while and I have yet to max out my Siren and didn't even touch my seven keys yet.
I can't wait to finally play Darksiders II though, I completed the original (PC version, on Steam that is) recently and it was a blast, the sequel got rave reviews almost everywhere I looked and the few videos I've seen of it (few, to avoid spoilers as much as I could) lead me to believe that it just looks to be in the veins of Zelda and Devil May Cry (again), an epic adventure filled with action. In fact the original already reminded me a bit of Legacy of Kain: Soul Reaver (more hectic though) mixed in with some Zelda puzzle solving style and I loved it.
I almost purchased The Walking Dead as well... not sure yet (in fact in was in my Cart for a moment). However, I've seen so many videos of it on YouTube that I pretty much "completed" the first season already (I unfortunately spoiled it that much but hey, I was intrigued and the guy playing commented well as he went through it for his first time as well, was kinda entertaining, and free). It looks interesting enough I guess. I'm still considering it right now, but I feel it'd just be a purchase out of curiosity rather than actual interest. I'll see... not saying no, but highly hesitant.
And also considering The Binding of Isaac, Legend of Grimrock, Don't Starve, XCOM Enemy Unknown and perhaps Bioshock Infinite.
