I know we're probably working towards this and all, but the one thing that'd just slay competition would be a full immersion VR. I mean, I don't mean the Oculus, I mean like we walk into a machine it scans for vital signs and we are physically transported into a game as like an avatar and we walk, run, etc. as the avatar and when our character is out if lives, we're removed from the game and come back into the conscious of now.

The machine would kind of work like the scanners in Code Lyoko or the machine wired to the Matrix in the Matrix films.
