Enduro Racer is Sega's attempt at porting the arcade game with the same name. Apparently they didn't manage, though, as the Master System version is totally different and plays more like an isometric version of Excitebike! The game is mildly entertaining for a few minutes, but the lack of any real features makes it one to avoid, unless of course you hold some nostalgia for it.
Also, the audio jack on the system works when docked, which is nice
Virtual Console incoming?
