Collector interest
A console port of New World Computing's first Might & Magic, this Secret of the Inner Sanctum brings a first-person dungeon RPG, normally a home-computer affair, onto the NES, an uncommon sight on the machine. American Sammy issued it in 1992 in limited numbers, hence a high loose value for a niche title. Its desirability stems from that unusual crossover between hardcore Western RPG and the NES catalog, prized by retro role-playing fans.
