A cave exploration game.
Lots of professional and amateur cavers and spelunkers can take go-pro cameras and scanners. They can take information about the caves and have it changed to rift images.
Would be a cool exploration game. Go to places that normal people cant. See details and things that may not be accessable to the average joe/jane.
Of course once you have the data you can manipulate it into a cool FPS game or horror game with it. Kinda like the movie THE CAVE.
It can be both educational and entertaining.
