Fist of the North Star (NES video game)
The U.S. version was shown at the 1988 Summer Consumer Electronic Show under the title "Ken the Great Bear Fist", which is the localized title used by Toei's international sales department. The title was changed to "Fist of the North Star" for its release in order to tie in with Viz's English adaptation of the manga. The cover artwork for the U.S. version depicts Kenshiro sparring with Toki, who doesn't appear in the game and never actually appeared in the "Hokuto no Ken 2" anime series outside flashbacks (as the character was already deceased by that point of the storyline). The NES version has some slight differences from its Famicom counterpart, which cuts the appearances of side characters at the end of certain stages (such as Bat and Rin at the end of the first stage), as well as the kanji that appear at the top of the screen when Kenshiro defeats a boss after striking its weak point at the start of the battle.
Fighting Fantasy
Several "Fighting Fantasy" titles have been released as video games, including seven "Fighting Fantasy" titles ("The Warlock of Firetop Mountain", "The Citadel of Chaos", "The Forest of Doom", "Temple of Terror", "Seas of Blood", "Appointment with F.E.A.R." and "Rebel Planet") for the Commodore 64, Amstrad, BBC, and Sinclair ZX Spectrum (1984) and "Deathtrap Dungeon" for the PC and PlayStation by Eidos Interactive (1998). On August 18, 2011 an adaption of "Talisman of Death" was released by UK developer Laughing Jackal for the "PlayStation Minis" platform (playable on the PlayStation Portable and PlayStation 3). 
Cambridge-based studio Inkle released another interactive version of "The Shamutanti Hills" for iOS in May 2013, and has since gone on to release all four parts of Sorcery! on iOS, Android, Windows and Mac.
