The version of Out of This World (Another World) released for the Sega Genesis/Mega Drive was ported by Interplay. This version, like the SNES port, was made more difficult, including more enemies, since it was normal for console games to be difficult in order to take longer to beat. It runs faster than the SNES port, but has less colors.
A similar version would later be released for the Sega CD, with a new soundtrack, bundled alongside its sequel, Heart of the Alien.
