Sister Sonic (cancelled "Sonic the Hedgehog" localization of "Popful Mail" RPG Sega CD game; 1993)
Sister Sonic is a cancelled role-playing video game in the Sonic the Hedgehog series. The game was set to be developed by Sega Falcom and was to be released on the Sega CD (Mega CD in Japan and Europe). Sister Sonic was going to be an American localization of the Japanese PC game Popful Mail, with the cast of characters being replaced with Sonic characters, as well as introducing Sonic's long-lost sister in place of Mail (the player character) herself.
History and Cancellation
In 1993, gaming magazine Electronic Gaming Monthly reported on a rumor of a new RPG game in the Sonic the Hedgehog series titled Sister Sonic and was possibly going to be unveiled at the Toy Fair in June of that year. Despite the report, Sister Sonic was not shown at the event.
Upon hearing about the game's existence, fans sent many angry letters to Sega Falcom, urging the developers to not change the game and release it in its original, unaltered state. Due to the overwhelmingly negative feedback, the game was delayed and eventually cancelled. Sega later released an unchanged English port of Popful Mail for the Sega CD in 1995. In a later issue, EGM made note of this event and the power of consumer's abilities to influence video game company's decisions.
No prototypes, screenshots, or videos of Sister Sonic have ever been released and it's unknown how much progress the game had made before it was cancelled.
