In the 1970. when gaming was just starting, there was another very popular trend for computer users and it was networking. Of course someone would come to an idea of putting those together. It wasn't hard to make that real. The multiplayer system was possible but what game do we make? There comes the game that most of computer users, usually "geeks" or "nerds", loved. Dungeons and Dragons. So it was created, the first ever multiplayer: "DUNGEON". Dungeon was written in either 1975 or 1976 by Don Daglow, then a student at Claremont University Center (since renamed Claremont Graduate University). The game was an unlicensed implementation of the new tabletop role-playing game Dungeons & Dragons (D&D) and described the movements of a multi-player party through a monster-inhabited dungeon. Players chose what actions to take in combat and where to move each character in the party, which made the game very slow to play by today's standards. Characters earned experience points and gained skills as their "level" grew, as in D&D, and most of the basic tenets of D&D were reflected. Daglow wrote in 1988, "In the mid-seventies I had a fully functioning fantasy role-playing game on the PDP-10 (a really old PC), with both ranged and melee combat, lines of sight, auto-mapping and NPC's with discrete AI." Although the game was nominally played entirely in text, it was also the first game to employ line of sight graphics displays. Its use of computer graphics consisted of top-down dungeon maps that showed the portions of the playfield the party had seen, allowing for light or darkness, the different "infravision" abilities of elves, dwarves, etc. There you have it.
