I'm not familiar with those games. My personal Sega saga began in the 80s with the Master System, and ended with the Genesis and Game Gear (which I still own!), and which I credit with sparking my original interest in computing technology. I did of course play plenty of Sega arcade games, but I didn't know until much later that they started out supplying coin-op slot machines and amusements to military bases in the 1940s and 1950s. It seems like the company went through 3 or 4 lifespans before they entered my awareness in the 80s.
