Yes, I watched Tron just the other day and was thinking about this, but I don't think it'd make for a fun mod. I don't make "spar" mods or sp mods where each round takes hundreds of turns. So, it'd be possible, but it isn't in the spirit of what I'm doing. The mod gravycopters1.tbm is a similar concept though, you're inside a low gravity cube, with a ball in each hand and a 360 chest. There is a target behind each player (loaded with triggers) and you have to hit it with the balls to win. Because you're inside a cube, you can bounce the balls off the walls, so it's possible to score quite easily with playable MP match frames and turn frames.

I wasn't suggesting a spar, just a slowed-down movement of the elbows and wrists so you can actually throw the disc.

How about a lacrosse mod? That'd be very fun if you could get it to work?
