Rocket League
No, we're not crazy for including Rocket League. Yes, we are absolute geniuses for even considering Psyonix' unexpected superhit. Come on, the best way to port a game over to a brand new platform like VR is to choose a concept that's as simple as possible. And we imagine a game of football between two small teams of RC cars is pretty damn simple.
Simple, but oh-so-addictive. That concept has made Rocket League a killer app across multiple platforms, so add in a VR headset, shift the game from third-person to first-person and you've got one of the most potentially amazing VR games of all time. Get on it, Psyonix. And remember to credit T3 when you do.
