I would love if WotC could extend GM’s guild to support their other IPs. Even if WotC is unwilling to do anything with the IPs, I’m sure that fans would love to make their own books.
I feel the same way about the Savage Worlds Adventure's Guild (SWAG), which is pretty much an extension of their free Fan License. SWAG products must deal exclusively with DTRPG, which I'm increasingly distancing myself from. I have no problem giving PEG their cut as a "licensing fee," but I don't want to give a percentage to DTRPG for hosting the content, especially since there is literally no alternative platform.
Combined with some of their questionable business practices lately, as well as some shoddy content, I'm moving away from Savage Worlds too. Their Fantasy Companion (still in beta testing) is trying REALLY hard to emulate the "feel" of 5e mechanics, and it's bogging down the otherwise smooth resolution of the core system. I took a gamble and vented my frustration on their forums and was surprised at the support I got. Don't think it'll change PEG's mind (nor should it, TBH), but it seems people agree it not the direction SW should be going.
I hear you. I've become increasingly disillusioned with ttrpgs as a whole because of the abandonware problem inadvertently forcing otherwise paying customers to sail the high seas, the takeover by leftwing proto-fascism, the general insularity of the market making it impossible for new creators to break in, so many fertile IPs being left to rot due to owner apathy and broken copyright law even if you can still buy ebooks (and whether they will continue to be hosted is playing Russian roulette now), venerable IPs being stuck in nostalgia ruts that prevent them from going anywhere interesting, venerable IPs being ran roughshod by new owners to constantly attract new players while leaving old players in the dust, that stupid supplement treadmill... I know some of these are issues with all IP industries, but the niche appeal of ttrpgs means they can't break out of it.
Want to make your own IP due to creative disagreements or the feeling that you can do something new, original, and fresh compared to the dinosaurs dominating the market? Well, you're unlikely to get a foothold unless a big company does something really stupid to alienate their customers enough to convince them to try other games, and those same customers will abandon your game as soon as the IP they previously liked makes a token effort to apologize.
Unless creators release their work under a creative commons license that keeps it in circulation (such as being hosted on the Internet Archive without risk of being DMCA'd) and promotes fan creativity (as opposed to worshiping teh "lore" as a religious text that cannot be deviated from), then I don't feel like investing in other people's work is worth it anymore. I feel like I'm better off writing prose fiction to sell on Kindle Unlimited or video games because those have a much bigger and healthier market.
