I've never experienced ROB. (I don't know how the hell I own a Gyromite cartridge) It only played Gyromite and Stackup, right?
How do you play Gyromite? I know it has something to do with having the gyros spin long enough to keep a gate open or something. And I don't know anything about Stackup. Aren't his eyes sensors, like the Zapper?
I've been thinking of getting a ROB lately, first I just wanted one to display with my Nintendo stuff, but I'm contemplating on whether or not to drop the heavy cash for a complete ROB with all the parts so I can play with it. But is it one of those gimmicks that's neat, but not something I'll want to play twice?
