The Siege of Avalon was the first and only game produced by Digital Tome. It was published by Global Star Software, which later became 2K Play, and when problems arose between them, Digital Tome disbanded. Originally, the game was available for download online. The first chapter was free; the other five were not. It was later released in an anthology on a CD, which can still be found either online or in some brick-and-mortar stores that don't move their video game inventory very quickly. A sequel called the Pillars of Avalon was planned, but never produced.
