Wow…I go to bed, wake up, go to work, and come back to this. I'll try to keep on topic and pass over the GSL/copyright/OGL/Paizo conversations going on here. I'll also be copying from responses I have made elsewhere (full disclosure).
This whole thing started because I received a call from a writer saying his 4E project had been dropped at Alea (I have mistakenly said Mongoose). Seeing how Paizo treats their 3rd party companies, I was hoping Wizards could do the same. From my perspective, there are two important issues to understand. The first regards product penetration. One of the leading factors attributed to the success of 3.0/3.5 what its open source content, resulting in every major publisher releasing a book under the D&D framework. Back then, you could copy the entire rule system; with the GSL, you can only reference, consequently forcing any consumer to own the core books to utilize a 3rd party supplement. By encouraging and supporting content, you allow a greater saturation of the 4th edition market, increasing the number of 4th edition books on a shelf—books that all require the same core volumes produced by one publisher.
The second issue involves mending and improving customer opinion. It will go a long way with both players and publishers if WOTC reached across with that olive branch. Consider the following: this open letter had been on LivingDice for nearly a week with not a single post. One mention by Morrus on the news page at EnWorld, and it exploded. Imagine the impact of Wizards doing the same thing, adding news content for GSL products. Creating a news page or running a blog for 3rd party content should not be a significant dent in WOTC’s advertising budget. As for the topic about a handout, I state at the beginning that this is about mutualism. But let's assume I was seeking charity. Every company sets aside money to improve its public image. It could be a charity or the sponsoring of a sports team. Supporting 3rd party companies improves public image…and they wouldn’t even need to attend a game. WOTC has the traffic and the original franchise. There is nothing I can do on my end to measure with that. I can't create a website and suddenly expect a million hits in a day. To prove my resolve, I'll say this: if WOTC were to allow such a blog or news page on their website, talking about 3rd party companies and their products, I would gladly write it for free, and I would do so for a month before even mentioning me work or my company. Offer me the soapbox and I'll shout how awesome 3rd party products are.
This thread and others have almost made an assumption that DEM is hurting, or planning on jumping ship. DEM made the decision early to embrace 4E, well before Pathfinder had ever existed. My group prefers and endorses 4E; they won’t touch Pathfinder. This is not an opinion I reflect. I have nothing against Paizo. I don't hate it. I have no opinion whatsoever. I love the art. I have talked with several of its writers, including Monte Cook. We at DEM prefer 4th Edition. I liked what it offered. And as Morrus eloquently and humorously put it, there is little competition here. When Amethyst was released for 3.5, we could claim no fertile ground; it had been tilled to salt by dozens of publishers before it. With 4E, it was a new field, ready to sow. Paizo has not reached out to DEM and I doubt they will, as we can bring nothing to the 3rd edition landscape that has not already been done. If they did, I would propose adopting it to my other writers. But this is the same group that hates Essentials as well, a series I actually enjoy. The fact they hate it didn't stop me from making Essentials classes for Amethyst in the next book.
Companies like Goodman and EnWorld have no issues promoting their own products to a wide base. Smaller companies have miniscule budgets to compete. Neither situation asks for a handout. We don't want Wizards "to do our job for us"; this assumes some of these companies can do so—like we could if we got off our asses. Anyone who knows me knows I work constantly. From LivingDice to CombatAdvantage, From Here to There, and I've got three game books being written simultaneously (Evolution, Factions, and Ultramodern4). The first Amethyst 3.5 book lost several thousand dollars, due mostly by its release a month before 4E. I keep at it because I love it, as do all who write for RPGs. I wouldn't accuse myself or any other company as being lazy.
The suggestion in the original letter is to encourage a mutually beneficial relationship, to create a community as Paizo has. I refuse to take the alarmist view that the GSL was originally designed to kill 3PP. Someone at WOTC had their heart in the right place (Scott). By actually entering the community or creating a community to share with companies supporting them, it encourages more of us move under their umbrella. There is almost a Windows / Mac parable at work here, with history repeating between the Apple OS and Android. Evolution is coming out regardless of this letter. Ultramodern4 will follow. This is not a death rattle. I'm not going anywhere (looks around the room)…at least not yet.
