Bad Badtz-Maru Robo Battle review. Classic Game Room presents a CGR Undertow import review of Bad Badtz-Maru Robo Battle for Game Boy Color developed and published by Imagineer. Sanrio's Badtz-Maru takes to the Game Boy Color in this amalgamation of a die-rolling boardgame and a gear-equipping RPG. It's all framed in the guise of a Robo-Battle tournament, where competitors pit their digital homunculi against one another in board game combat, complete with stat-altering spaces, wormholes to entirely different chunks of the board, HP-recovery houses, shops, and other effects. It's a nonlinear take on a classic gaming style. This video review features video gameplay footage of Bad Badtz-Maru Robo Battle for Game Boy Color and audio commentary from Classic Game Room's TJ.
