It will have three stages.

The first stage is the Nomic stage, where players volley for rules and set the groundwork for stage two.

Stage two I think might be something thoughtful, like a series of puzzles or maybe something mystery oriented.

Stage three in that case should have lots of action. Car chases and explosions, that kind of thing.

Maybe you could switch two and three around depending on which flows better.

Stage two should also set the groundwork for stage three.

What do you think?
Do you have any ideas for how to accomplish this?
I really can't think beyond stage one...
