OK, gang, you read it here first. The game is going to be called "Luminosity" and is going to involve lights, and darkness, and be insanely cool to play and watch. (JMHO) The entire thing won't be played in darkness (too hard, and hard for the spectators, even if the robots have lights on them), but there will be some aspect of it that involves darkness (perhaps a tunnel that the robots have to navigate?).

Maybe glowing tennis balls.

No water, though.
