I agree with RSpawn. It's a nice contest idea but not very planned.
5 levels are relative. You can have BIG, COMPLEX levels and small, less complex levels. I want to join with a turn based strategy game. So what games are allowed anyway?
"Panzer General" for example is a wargame and strategy game, too. But I think it's not the type of game Mark thought of.

Make a list of rules and maybe some different prizes. Anyway I'd like to see some money in my pocket.

@scary_man: pathfinding as resource?! That's what's necessary for a strategy game so I think everyone will have it already when the contest ends...
