My cousin was the only person I've ever known to own a Master System. I didn't even know that he had one until I got a Genesis. He did have a couple of games that I was envious of, though. I really liked The Flash television show and was jealous that there was a game for the Master System. Also, I remember Superman being a better game on the Master System than the Genesis because you could fly whenever you wanted to! I liked the Spy vs. Spy game, too, good fun. And Sega made Chess for the Master System but not for Genesis, I never understood that.
