Moria is a dungeon crawl style role-playing video game developed for the PLATO system beginning around 1975 by Kevet Duncombe and Jim Battin.

Some Moria players preferred to "role-play" as their fantasy personas[1] instead of merely playing the game.

Moria allows 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.

In an effort to "modernize" the lessons, color was added by an intern in 1994 at University Online after the CYBIS system and its content was sold to them.

CYBIS (short for CYber-Based Instruction System) was the new name for PLATO after CDC sold the trademark to The Roach Organization in 1989.
