The Last Ninja is a series of exploration/combat/puzzle adventure games from System 3, originally developped for the Commodore 64 in 1987. The first game was met with wide praise as one of the best games ever of its type, and featured very detailed graphics for its time.
The game was sequelled by Last Ninja 2 (1998) and Last Ninja 3 (1991) and was ported to several 8-bit and 16-bit systems.
There was, however, quite a naming confusion. In 1990, System 3 released "Ninja remix" for 8-bit systems, which was Last Ninja 2 with remade music and slightly enhanced graphics. However, as the first game in the series hadn't been released for the 16-bit systems at the time, the "Ninja Remix" release for the 16-bit systems was the first game The Last Ninja instead. Thus "Ninja Remix" is either the first or the second game, depending on what platform it is for.
The Last Ninja 2 was also released on the NES, under the name "The Last Ninja", addding to the confusion.
After Last Ninja 3, that never reached the fame from the previous two games, there were plans for Last Ninja 4 that never saw the light of day.
