Let's have a try at that.

Take some reasonably well-known formal system.  Players take turns 
adding additional axioms. Before his turn, a player may challenge his
opponent's last move.  That player wins if he shows that the opponent's 
most recently added axiom is redundant, or that the current set of axioms 
is inconsistent.
