Goat Simulator, if it includes the DLC's. Otherwise it's not that much of a discount.
Journey and Shadow of the Colossus: I haven't played them, but I've been considering getting a PS just for those and a handful of other games.
Tomb Raider is a guilty pleasure of mine. It's a bit of a walking simulator, but I liked it a lot.


I've been playing a lot of Overwatch lately. If you're even remotely interested in the genre, you'll get your monies worth. I recommend playing it on PC on US servers.
If any of you are estranged SC2 players, Blizzard has made a bunch of updates recently. Co-op is really popular right now, and it looks like they're going to make Wings of Liberty free to play. Arcade and custom games have been F2P for a while even though this was poorly advertised.
