MUDs, or Multi-User Dungeons, are text-based online games that allow multiple players to explore virtual worlds, solve puzzles, and engage in combat. Players interact with the game environment and each other through typed commands, creating a rich narrative experience. MUDs often include elements of role-playing, allowing users to create characters and develop their skills. Originally developed in the late 1970s, MUDs laid the groundwork for modern online gaming and virtual communities. They have inspired various genres, including MMORPGs (Massively Multiplayer Online Role-Playing Games) and text-based adventure games. MUDs continue to have a dedicated player base, celebrating their unique blend of storytelling and social interaction.
