#2. Sonic the Hedgehog | Released 1991
Sonic put Sega Genesis on the map as the counter to Nintendo’s Mario (Playstation and Xbox were still in the works at the time); Although Sega has shifted to third-party software development since the early 2000s, Sonic continues to remain popular. He even appears in the 2012 Disney film Wreck-It Ralph with a small speaking role.
