Super Robot Taisen: Original Generation

Super Robot Taisen: Original Generation (スーパーロボット大戦ORIGINAL GENERATION, Sūpā Robotto Taisen Orijinaru Jenerēshon) is a tactical role-playing game for the Game Boy Advance, developed by Banpresto and published by Atlus (Banpresto in Japan).
The game was originally released in Japan on November 22, 2002, and stars various original characters created by Banpresto for their Super Robot Wars series. Like the much earlier Super Robot Wars Gaiden, the game features no licensed mecha or characters at all - instead, it uses only Banpresto's own creations, in an original story. The games sold well in Japan, and later adapted for a short animated OVA called Super Robot Wars Original Generation: The Animation, which takes place after the second game in the series. A television series, Super Robot Wars Original Generation: Divine Wars, retells the story of the first game. Original Generation was released in the United States on August 8, 2006. It is the first game in the Super Robot Wars series to ever be commercially released overseas, since, unlike the rest of the series, it contains no characters from other media, therefore, no legal entanglements were involved in a foreign release.
A sequel, Super Robot Taisen: Original Generation 2, was available on February 3, 2005 in Japan and was released in North America on November 21, 2006. On June 27, 2007, Super Robot Wars: Original Generations, an enhanced remake of both Original Generation games, was released in Japan for the PlayStation 2.
