Sega delivers a convincing Master System conversion of one of its most striking arcade hits, tweaking the coin-op game's design in small ways that made for a more console-friendly experience. We've seen similar revisions made to previous Master System games, too, but the difference is that those games weren't Shinobi. A fast-paced platform shooter, Shinobi saw Sega offering its own take on a burgeoning format of the time. It arrived a little later than most of the big breakout titles in the genre, but that just meant that Sega had time to learn from everyone else's missteps and deliver a nearly flawless take on the genre. It also underscores the company's most direct rivalry... no, not Nintendo.
