Yeah, that would easily work. Mind, I'm not suggesting that a stage has to be absolutely constant for it to work, my example before using racing games doesn't use constant stages, and users can go at ther own pace, but the problem with multiple video layers in that genre is deciding how to progress through the stage. Do you follow a specific player or move through a portion of the stage where you can view the most people. Maybe it would work better in the style of Gran Turismo replays with fixed cameras recording the race.
