I'm not training these days but as soon as I decide to I want to suggest this game.
Start in pairs one at a time in mount on the far end of room across from front door against a wall. Bottom guy wants to leave gym. Top guy wants to submit. If top man submits next pair restarts. Otherwise next pair is dispatched as they progress towards the door. When restarting switch sides.
