Bubsy is a series of video games created by Michael Berlyn and released by Accolade for the SNES, Mega Drive/Genesis, Atari Jaguar, the PC and PlayStation in the early and mid-1990s.
Though the games were platform games similar to Super Mario Bros. and Sonic the Hedgehog, the eponymous anthropomorphic bobcat never came close to the popularity level of the two bigger name mascots, despite early hype that made Bubsy out as "the next Sonic the Hedgehog." Nevertheless, the first Bubsy was a big hit and met with positive reviews for the SNES version. The success of the first game spawned a series of Bubsy games, though none of them were able to reproduce the success and acclaim of the first game.
