I am talking about TG settings, not "10". I never have mine set to 10, but I might try it to see how I do compared to those scores you mention. I think the one I scored a million on last weekend was probably set at TG. I am aware that the inventor of Robotron, Eugene Jarvis, says the only way to play the game in on 10, otherwise it is too easy and you can play forever...but I certainly can't play the game that long. I start to wear out physically around 1.5 million. I have no idea how someone managed to play this game for two straight days, but I'd guess they weren't a middle aged man like me.
