I see a Robotron pin as having tons of drop targets like the "bad guys" on Cactus Canyon. They'd just start popping up and advancing toward you from multiple directions. If it advances too far, your flippers die and you lose the ball. Multiballs and extra balls (like extra lives) would have to be easy to get, and you'd have to knock down the targets to get to certain ramps, standups, or holes that represent the different family members. Certain "levels" could have crazy magnets in various locations all over the playfield that whip your ball around like on the tank stage of Robotron. I think it could be kind of cool, but definitely not a deep game!
