As modifiers to the score, you could use the robot's OPR and DPR perhaps.
Maybe a game could be played where you have one robot as "your team's" robot. You could either draw random robots from a deck of robot cards for alliances (for qualifier matches) or draft them (as in the elims) and can play cards that would affect the outcome (opponent tips, G22 penalty, etc.) from your hand, and as was mentioned roll a die or use a random modifier to determine the score. This might also be a game where more than 2 people should play, if you want to really have the alliance thing going. Like a 3 on 3 game?
