Like silent films, old time radio, male grooming and slide shows, the text-based game is a largely dead art form. Like the other examples, it's uniquely enjoyable and was snuffed out by its flashier, less imaginative offspring in the pursuit of realism and technology. (Don't get me wrong, I think GUIs are la mamá de Tarzán and I even crossed the security line at Xerox PARC on a nerd's tour of historic Silicon Valley to drink from the fountain where the Xerox Alto was born back in 1973.) But the quiet pleasures of text games are enjoyable in their own right and with a whole generation almost incapable of communicating through any means except texting, the text game seems ripe for a comeback.
Instead of using graphics, text-based games use prose to tell the story. Players type specific commands to such as "go north" to play. A lot of the fun (and frustration) comes from having to type them precisely. For example, if you type "omg go north lol!!!," the computer will reply, "You used the word north in a way I don't understand." It may be frustrating at first to not punctuate every command with "lol," but once you get the hang of it, you'll find text games can be highly addictive. Besides, frustration puts hair on your chest.
