Wow... lots of discussion going on here.
Psion, it sounds like you and we will just have to agree to disagree.
I've got a few comments and queries, as follows:
It's true, we're not adding to the SRD ( yes, I do know about it

), but it doesn't affect the quality of our product. And, to me, that's the most important thing - putting out quality products for gamers. We're certainly contributing to the gaming world, even if not specifically to the OGL.
And we're not only publishers, we're gamers and consumers just like everyone else. We're not some corporate giant by any stretch of the imagination. Only a little over a year ago, the whole company was four guys working out of a basement. (We've tripled in size! Woo hoo!

)
You said that many publishers collectively working together strengthens the whole. Ok, I can't disagree with that statement, but I wonder if it really applies. If all d20 publishers were working together on one campaign setting, I would definitely agree. But they're not - they're working on their individual worlds and settings, pulling whatever they feel is appropriate from the SRD and OGL. So you've conceivably got several different versions of the same rules. To the average consumer, not the d20 publisher or avid follower, that surely must be confusing. And what happens if the OGL disappears next week? (No, I don't have any inside info, I'm just saying that you never know).
I'm not against d20 or the OGL at all, by the way. I have Fantasy Flight, Iron Kingdoms, and other d20 books gracing my shelves at home.
Also, I can't speak as to the exact legalities of our contract with WotC, but the OGL didn't even exist when we first made our agreement with them (to make Kingdoms of Kalamar an official D&D world). It wasn't even an option.
We could be having the same product as a d20 system product for much less.
Ok, I really have to question this one. Do you mean that if our products were simply d20, they would be cheaper? If so, that's certainly not the case. We give our fans the best we can, packing our products full of text and info, and keeping them all as affordable as possible.
All rightly, hope that cleared up a couple things.
