Overlord is a strategy video game released by then-unknown Virgin Games in 1993, among the last titles for the original Nintendo system. The game is a port of a PC game titled "Supremacy" and is relatively rare for a NES gamepack, with most copies only available online. Overlord is also noted for having very few sounds and little music in it (mainly just the title theme composed by Jeroen Tel), both not characteristic of most video games. The gamepack also has an internal battery to retain game saves.
