After Hours  The Open Game License: A case study in open source
markets  The history of the roleplaying game industry in
general, and the Dungeons and Dragons game in particular, serves
as an interesting case study in the relative benefits of
openness in business models.  History often presents us with
valuable lessons. Sometimes, those lessons come from unexpected
directions, as in the case of the roleplaying game (RPG)
industry in general, and the Dungeons and Dragons (D&D) product
lines within that industry in particular. Believe it or not,
this industry's history has a lot to teach those of us who
develop, support, or sell software professionally. This is
because, when it comes to a lot of the particulars of
development and marketing, the RPG and software industries are
more alike than different. They both depend on knowledge workers
and creative developers, they both involve attempting to make
money off of works that can essentially be copied and
distributed for free in today's Internet-connected world,
