Push My Chair

Office workers on wheeled chairs try to shove each other out of a ring, armed with whatever was on the desk. That is the entire design, and it is enough. The chairs keep rolling after you stop pushing, so every attack costs you position, and the arena edge does more damage than any weapon in the game. Played against the computer it is a short joke; played against someone sitting beside you it becomes a question of who is willing to lean further out over the edge.
