Normally I don't link much to other blog posts, but I stumbled across this recently, and this is a gold-mine of history about the development of d20, D&D 3rd Edition, the buyout of TSR by Wizards of the Coast, and the subsequent buyout of Wizards of the Coast by Hasbro.
What an amazing discussion! You'll have to read beyond the post, into the comments, but this is really good stuff. At least as good as the famous salon.com article "Death to the Minotaur" by John Tynes. Probably better, actually.
I've got an interesting relationship with Grognardia; I'm not really a fan of the movement he's supporting or blogging about, and much of what the blog's author and frequent commenters say frustrates me from time to time, but at the same time, there's a wealth of interesting material showing up over there consistently, sometimes almost by accident. So I try to keep my eye on it anyway. I've never been gladder that I did than today, reading all these posts linked here.
