In the age of smart devices and instant entertainment, can a medium as old as MUDs survive? Driven entirely by text, these Multi-User Dimensions ― or Dungeons, or Domains, or so many other options that they’re often called MU* ― are virtual worlds that consist entirely of text. Often outfitted as RPG-style games, these platforms are also home to niche internet communities on the fringes of the web. The servers are accessed via a telnet client, which is easy enough to launch in a command line. But there are a few popular applications that many longtime players opt to use. They’re rather reminiscent of the various chat programs built up around the IRC protocol, and provide simple functionality like logging, colors, aliases, triggers, timers, and even mapping.
