Thieves' Guild is a multi-player strategy door game for Atari ST and PC-compatible bulletin board systems. In Thieves' Guild, players explore a large medieval world, and advance through thievery, spellcasting, and combat. There are 25 different towns to discover and explore, each with a unique feature.
Like many other BBS door games, Thieves' Guild is asynchronous. Gameplay is turn-based, with a set amount of time available to play each day.
Paul Witte created Thieves' Guild in 1988 for Mythyn Software.
Robert Fletcher and Herb Flower developed a graphical front-end client for Thieves' Guild for the Atari ST. The pixel-art graphics for this client are surprisingly detailed, and among the best of any other BBS door game.
Thieves' Guild is also unusual among BBS games in that a printed map was available for purchase from Mythyn Software. The map was drawn by Flower, and detailed all the locations users could find in the game.
