Grand Master Nintendo

Grand Master is a virtually unknown and underappreciated action-RPG for the Famicom. It was developed by Soft Machine and published by Varie in Japan and never saw an official English release. It features a Western fantasy theme, and while the story might be cliché, it was told through multiple story branches the player can discover which was a very forward thinking idea at the time. The gameplay is pretty solid as well and almost feels like an NES version of Link to the Past. But perhaps due to the obscure nature of the developer/publisher and the advent of the SNES, the game was pretty much forgotten and as such it has remained an obscure Japanese gem.
