Sister Sonic

Sister Sonic is a canceled localization of Popful Mail announced in late 1992. Originally, the plan was to replace the existing cast of the game with Sonic the Hedgehog characters, including Sonic's long-lost sister, Sister Sonic. Due to many angry letters sent to Sega Falcom (the name which would be used for the Sega and Falcom team) by fans of the original PC game, it was decided to cancel this port and instead settle on a more direct port of Popful Mail to the Mega-CD.
