* AbsenteeActor: This is one of a handful games in the franchise where both Sonic and Eggman are completely absent. Tails is the only regular appearing, and all of the other characters are unique to this game. Sonic and Eggman are only mentioned in passing in the manual (and Tails uncovered Witchcart's plot in the first place because he assumed the islands rail like system was a new scheme being set up by Eggman).
* AscendedFanon: Witchcart's first name in the [[ComicBook/ArchieComicsSonicTheHedgehog Archie Comics]], Wendy, is taken from Wendy Witchcart, a FanNickname with AddedAlliterativeAppeal that circulated online.
* HilariousInHindsight: Rail Canyon would later become the name of an (unrelated) stage in ''VideoGame/SonicHeroes.''
* NoExportForYou: Prior to being included in ''VideoGame/SonicAdventure DX'' and ''Sonic Gems Collection,'' the latter of which mercifully grants a save state feature, making the game much more feasible to win.
