Answer: Multi-User Dungeon
There were long textures of rich textured video games and massive online universes that featured text-based games. The 1970s gave rise to the first of these text-based adventures and the very first to offer multiple players the opportunity to eat together.
The first text-based game that received much attention and play was Colossal Cave Adventure designed by Will Crowther in 1976. Due to the success and the charm of Colossal Cave Adventure a group of students was built at MIT Zork which was then ported to FORTRAN IV by another student during the short period of time Zork was called for Dungeon (TSR, Tactical Studies Rules, soon forced a name change back to Zork ). As fun as these games were with their Dungeons & Dragons inspired hack and slash adventure were play a lonely experience. It was you against the machine without the opportunity to accommodate in a virtual space with your friends.
No chance, that is until 1978 when Roy Trubshaw and Richard Bartle, students at the University of Essex, created a game like Colossal Cave Adventure and Zork (as they knew as Dungeon ) that enabled multiple players to go together and interact with adventure. To commemorate the Dungeon variant of Zork named the Trubshaw game MUD ( Multi-User Dungeon ). The game was played on small networks until 1980, the University of Essex was connected to the ARPANET. From the humble beginnings of the two students' side projects, the whole concept of MUDs took off. In the 1980s and 1990s, MUDs (and variants like MUSHes and MOOes) were where you went if you wanted to play a fun and low-bandwidth-friendly online game.
The original MUD, now known as MUD1 ] to name it as the original MUD game, is still online and ready to calculate all text-based adventure you can handle.
