A Whole New Game

It would be an interesting game if you could do the following:
Set up timing computer to:
Establish length of game
Establish number of "round" (or equivalent) during that time period
the timing of the rounds would be random. and the duration of each round (given a LOT of time) would be such that people would relax again between rounds. Thus it would test reaction-to-readiness as another factor of skill. It could be applied to anything from board games to team sports.

It might be difficult to keep the audience engaged though. But it's worth further consideration.
