I would definitely see it as support for d20
Modern!
In fact...country or region books for Modern gamers...hrrrmmm...
The quote from Mr. Dancey spells it out: OGL was meant to sell players handbooks and stifle competitors. The fact that other companies have created alternative approaches to fantasy gaming using the OGL probably gives the Wizards staff nightsweats, since it "splinters the market" (I believe that was the phrase I've heard), but as a consumer who prefers these alternatives to The World's Most Ubiquitous Role Playing Game, I think it's ducky.
OGL?
Great for consumers - may not have worked out quite the way Wizards thought it would, though (and thank goodness it didn't!).
Oh, and books like
Thieves World and
Black Company aren't support for
Dungeons and Dragons? That seems like a terribly narrow view of what can and can't be done with the rules options in these books. I suppose if one takes the view that
Dungeons and Dragons is its own specific fantasy genre, than this might hold true - the options are not "more of the same." On the other hand, if
D&D is truly a "generic" fantasy RPG, how could anything in those books be any less 'core' than the content in
Unearthed Arcana?
