I think a game were u used ur expressions to taunt other people would be fun, you would have to scare the other person with the expressions that you had. You and the person you were against would take turns and there would be a fright meter for each person the first one whos meter gets to the top looses.
Or a game that tests you eveil, or good. You would use good, or evil powers against another person of the same alignment (or close to the same) and the winner would get another power for that alignment ( sorry if i dont make any since).
