SilverMUD is a setting-agnostic multiplayer roleplaying game which is played over the internet. It gives a gamemaster the same flexibility they have to improvise and create content as they would have at a table-top, by allowing game content to be programmed and altered on-the-fly, using an integrated Scheme interpreter. It can be played as a multi-user dungeon, or a “terminal-top” roleplaying game, depending on how you decide to configure it.
