Sonic The Hedgehog (Cart Only)

The start of Sega's challenge to the Big 'N' can be traced back to this icon of a hardware battle - not that at first glance Sonic gives the appearance of a guerrilla soldier. But with the super slick gameplay, fast flowing as reflex nerves fire off repeatedly, Sega captured a key slice of the market and ensured the legend of the Saturn and Dreamcasts came true. As such a worthy contender for the gaming history museum.
