Fist of the North Star (NES video game)
Fist of the North Star is a side-scrolling action video game produced by Toei Animation and developed by Shouei System for the Nintendo Entertainment System (NES). It was first released in Japan under the title on April 17, 1987, being the second "Hokuto no Ken" video game released for the Family Computer (Famicom) by the anime production company (which briefly entered the video game publishing business after their success with the original "Hokuto no Ken" game for the Famicom in 1986), while also serving as a tie-in to the "Hokuto no Ken 2" anime series which began airing on Fuji TV a few weeks earlier. Taxan published the localized NES version on April 1989, making it one of the earliest "Fist of the North Star" products released in the U.S. alongside Viz Communications' English adaptation of the manga.
Crest of the Stars
"Crest of the Stars" was released in Japan in 1999 and in the United States by Bandai in 2001. At the end of 2002, TechTV announced that "Crest of the Stars" was to be one of the initial titles as part of their new "Anime Unleashed" programming and began broadcast at the end of 2002 and through 2003. Following the closure of Bandai Entertainment in 2012, Sunrise announced at Otakon 2013, that Funimation had licensed "Crest of the Stars", "Banner of the Stars" (Seasons 1 & 2) and "Passage of the Stars".
Several episodes contain a brief introduction about the history, culture, purpose and perception of the Abh and its empire. 
Roughly a year after the Anime finished airing, at the end of May 2000 Bandai Visual released a video game adaptation for the PlayStation. It features a story inspired by both the Crest of the Stars and the Banner of the Stars novels, incorporating some of their characters. The game consists of 67 different space battles, with a story split in two paths and three possible endings each.
