By 1978-79, PLATO MUDs were heavily in use on various PLATO systems, and exhibited a marked increase in sophistication in terms of 3D graphics, storytelling, user involvement, team play, and depth of objects and monsters in the dungeons.
PLATO MUDs are often ignored by historians and by the creators of other MUDs whose work came later.
Inspired by Adventure, a group of students at MIT in the summer of 1977 wrote a game for the PDP-10 minicomputer; called Zork, it became quite popular on the ARPANET.
Zork was ported, under the filename DUNGEN ("dungeon"), to FORTRAN by a programmer working at DEC in 1978.
The history of modern massively multiplayer online role-playing games (MMORPGs) like Ever Quest and Ultima Online, and related virtual world genres such as the social virtual worlds exemplified by Second Life, can be traced directly back to the MUD genre.
