Mortal Kombat X. Netherrealm really turned the series around for the better in 2011, and it looks to be getting even better with the sequel. Just wish the DLC wasn't so badly priced. Bastion is my second pick, since most people who cared to play it already have on PC or Xbox 360.
Mortal Kombat X is seriously making me want to buy a PS4 right now. I've been holding off but I'm cracking. Omega Quintet looks interesting, too. I'm ready for JRPGs to start hitting the PS4, to be honest.
