The Game Boy Advance version of Planet of the Apes is somewhat different, visually, to the Game Boy Color version, although it is basically the same game underneath. Graphically, the GBA version goes for a “digitised”, more realistic look, which I don’t think is as appealing as the pure 2D drawn look of the GBC version. It makes the game look more like an early ’90s Amiga game, which I think dates it significantly.
Planet of the Apes for the Game Boy Color was developed by Torus Games/Visiware and was first published by Ubisoft in 2001. It is based on the 1968 film of the same name, which in turn was based on the 1963 book by Pierre Boulle. Actually, to be more accurate, the game follows the plot of the 1970 sequel, Beneath the Planet of the Apes, more closely than it does the first film, where Brent (played by James Franciscus) crash-lands on a post-apocalyptic Earth on a rescue mission to find Taylor (Charlton Heston), and eventually finds himself held prisoner in an underground city run by telepathic humans.
The PlayStation version of Planet of the Apes was developed by French company Visiware and published by Ubisoft via Fox Interactive in 2002. The game was also released for Windows, and that version was released the previous year in 2001. It was actually the first video game ever to be based on the Planet of the Apes franchise. Although it is part of the same family of releases as the Game Boy Advance and Game Boy Color versions, it is a third-person 3D game and not a 2D platform game, like the handheld versions.
