I want there to be a game that is as much a mental challenge as physical, but not forced like chess boxing or only mental for the coach like gridiron. I want a game where you as a player will only succeed if you are mentally and physically fit and can use both of those skills at once. Maybe what I'm thinking of is some kind of obstacle course maze.

PS - Maybe it's unnecessary.
PPS - Because there are enough games to challenge either mind or body.
