In RARRR!!, players first draft monster power cards in order to build their perfect monster, then draft power bid cards to fuel their monsters' rampages through cities. Cities are destroyed using a bidding system, and players are limited in their bids by the amount of each type of power that their monster possesses. Will you build a super fire-spewing dragon monster, or a more balanced monster that can flatten cities time and time again for the long haul? Either way, it's not a good day to live in the metropolis.
