Moria is a dungeon crawl style role-playing video game first developed for the PLATO system around 1975, with copyright dates listed as 1978 and 1984. It was a pioneering game, allowing parties of up to ten players to travel as a group and message each other, dynamically generating dungeons (instead of pre-computing them), and featuring a wireframe first-person perspective display. One of its authors, Kevet Duncombe, claims not to have read the works of J. R. R. Tolkien or heard of Dungeons & Dragons at the time development started, but he was aware of the PLATO game, dnd.
