If a company wants to keep his customers, it tries to make them happy. Have you seen a book about flowers and gardens in D&D? No. Why not? Because not many people would like it, and hence buy it. .
This has nothing to do with the conversation, therefore I have no rebutal.
Customers would like to have access to a character generator with material from the books they buy. And yet, WotC doesn't want to allow character generators to use that material. Or even other material-producing companies. Wouldn't it be better if anotehr company could use feats from the books other than the Core three? .
No, it would be bad,very bad. It would prove that WOTC is giving perfered treatment to software makers than people who use the OGL/D20 licences. At that point, the D20 Brand would be diluted and open up lawsuits than nobody needs.
Seriously, it wouldn't harm them very much if a NPC in a book from another company had the feat Blooded (from the FRCS) instead of Improved Initiative (I do not ask WotC to let another company reprint the feat and the description, just to let them use feats and PrC from their non-Core books). If a DM runs only official adventures, he will never get to use anything from the BoVD, for example. And yet, everybody thinks that's fine. Companies who produce other rpg have the same stance, but at least, they re-use their own material. WotC won't, because the consumer is supposed to only have the three Core rulebooks. So, if a DM who runs only official adventures has 4 players who take each a PrC, it means that all the PrC from all the splatbooks except 4 are money he threw out the window. I have troubles understanding how people can say WotC does the right thing, from a consumer's point of view.
The last part of your statement is so confusing I don't know where to start. The fact is that a being a DM and running a D&D game is totally differant that making and distributing software.
Any DM is free to use any any book he wants in his game, I myself have used "Heart of Nightfang Spire" with characters using information from "Oriental Adventures, Sword and Fist, Song and Silence, Masters of the Wild, and Tome and Blood". As a DM, I'm free to modify any game I want with information from BOVD, (And I am, updating Die, Vecna Die with it right now). I'm Also getting to run a Dragonstar game and I'm thinking of getting the new book from perpitrated press to flesh out the firearms section.
So what about about companies who want to use materials that have not been released to the SRD?
Simple.
I would suggest that they contact WOTC to see if they could use the information in thier books.
No I can just guess what your about to say poilbrun. Your going to say, I bet that they wouldn't do that in a million years.
Well take a look at "Tome of Horrors". Its a book that was created by the fine folks over at the Creature Catalog, in conjuction with Necromancer Games. WOTC worked with them to make sure monsters were not duplicated and allowed them to update monsters from 2e and 1e games.
