* AwesomeMusic:
** The music is considered one of the best Commodore 64 soundtracks of all time.
** ''Twisted Dreams'' heavily features Music/MachinaeSupremacy on the soundtrack.
* CultClassic: Despite Nintendo stomping the original computer versions in the US, the series enjoys a loyal fanbase.
* GrowingTheBeard: ''Twisted Dreams'' seems to be aiming for this. For one, it's not a simple run-and-jump Mario clone like it was in the past. Secondly, the level design and the music are both [[DarkerAndEdgier a far cry]] from the chipper, cute themes players were accustomed to in the previous titles.
* HilariousInHindsight: That the blatant Mario copy was remade twenty years later for a Nintendo system.
* PolishedPort: [[http://pixelglass.org/GianaSistersSE Giana Sisters: Special Edition]] is a fanmade revamp of the originally bare bones Amiga port. The graphics have been almost completely redone from scratch based on the DS game including unique enemies and much smoother animations, a fleshed out color palette using new background tiles and making use of all 265 colors from the system, the music has been upgraded to the Amiga's higher quality along with new sound effects, and the intro from the DS game has been ported.
* SerialNumbersFiledOff: So much, that Creator/{{Nintendo}} threatened to sue unless the game was pulled from shelves, so the original wasn't sold in the US after a month. [[JustifiedTrope Justified]] in that the game was created so computer users could play Mario too, since Nintendo [[NoExportForYou refused to make computer games]].
* SurprisinglyImprovedSequel: ''Giana Sisters DS'' built upon the first game with more expansive level design, along with adding more unique enemies and a more diverse soundtrack.
** EvenBetterSequel: ''Twisted Dreams'' takes everything that worked in ''DS'' and cranks it [[UpToEleven up to eleven]], from level design and [[NintendoHard difficulty]], to the soundtrack featuring [[CrowningMusicOfAwesome the composers from first two games and Machinae Supremacy]]. It's been called one of the most original titles of its year, which is a far cry from the ''Mario'' clone that it once was.
* SweetDreamsFuel: The ''DS'' game is this. Cute Giana's levels in the sequel, on the ''[[NightmareFuel other hand....]]''
* VindicatedByHistory: The re-imagining is now on a Nintendo system: the {{DS}}.
