I was going to download this last night, but then I saw how big the demo was...218 MB. I would have stayed up much later than I wanted.
What really surprises me is that there is not a Linux game for AD&D 1e or 2e. Every LInux afficianado I know who is over the age of 30 has a history of AD&D, and for most it seems a fond history. All the younger folk mostly have rpg memories of computer games it seems.
