* 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.
* SerialNumbersFiledOff: So much, that Creator/{{Nintendo}} successfully sued, so the original wasn't sold in the US after a month.
** RealLife JustifiedTrope: 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}}.
