Borderlands 2 on Steam a couple of days ago, plus the Mechromancer DLC. Was hesitant at first as the first Borderlands kind of bored me, but I am really glad I decided to go for it. Much better, more fleshed out game than the first.
Unless you count the pre-order I made on Amazon yesterday for the Tomb Raider Collectors Edition. Than that would be most recent I guess. It's not here yet, but I did technically buy it.....so.....yeah.
Next up would be maybe Crysis 3 for PC pending impressions upon release. If Crysis 3 will be good for anything, it's the eyeballs and earholes at the very least. But definitely Rayman Legends.
