Batman Arkham VR is a fantastic game. Has a couple of shortcomings, but great nonetheless.
For sports, Oculus has a Sports VR title that is pretty fun - you play ice hockey, basketball, and football in first person. Really well done, even if they're pretty much mini-games (you don't run or skate around).
I can't wait for Star Trek. I played the demo at E3 last year and it was unforgettable. Can't wait for more of it.
What else would I want? Hmm...honestly I want to be able to watch 3D, HD sports. LIVE. THAT would be a monumental achievement.
