Released on 26th September 1986 in Japan, Akumajō Dracula (translating as: “Demon Castle Dracula“) was the very first release in the Castlevania series, predating the MSX version of the game by about a month. Konami released it on the Famicom Disk System where it quickly became a hit with Japanese gamers.
It began a long-running series of platform/horror-themed video games and set the template for the Castlevania series as a whole.
