Probably just Mario at launch, thank god, haha.
Wolfenstein 2 I'm sure I'll get eventually, but I haven't even finished the DLC for the first game yet.
Assassin's Creed I'll probably also get eventually, but even with the extra year off, I still have a backlog of several Assassin's Creed games. I tried AC Rogue (too similar to 4, which I played a ton of), haven't even started Unity, and don't even own Syndicate yet.
Mordor I think I'll just wait for a sale. Looks like fun, but there's so much else out and I don't particularly feel like supporting all of WB's shadier shit they've added to this game.
