what was the better system, the snes or sega's genesis. during their release and heyday both sega and nintendo were fighting for the top of the market in what was known as the "console wars". sure there popular games on the genesis like sonic the hedgehog and ecco the dolphin but the snes had nintendo's plumber in the mario series with super mario world that sold 20 million copies. along with donkey kong country series that produced a 3d like quality on the snes. so which is the superior console.
