The Great Giana Sisters

The Great Giana Sisters is a platform game developed by Time Warp Productions for the Amiga, Amstrad CPC, Atari ST, MSX2, and Commodore 64. It was released in 1987 and published by Rainbow Arts. The Commodore 64 version was programmed by Armin Gessert. Graphics were designed by Manfred Trenz.

Rainbow Arts was forced to withdraw the game from sale almost as soon as it was released and cancel release of the otherwise completed ZX Spectrum version, under pressure from Nintendo's legal arm, because of the strong resemblance to Nintendo's Super Mario Brothers game. The cover of the C64 version, published in the UK by GO! (a sub-label of US Gold), went so far as to taunt Nintendo's game with the tagline "The brothers are history".
