There is an inherent problem with proposing a "master" anything – on the Internet as much as on Steemit itself.
The only people likely to hear it are the people who don't need it and the people who need it are unlikely to hear it.
The only thing that really works is a sort of emergent standardization, where we just get in the habit of doing it ourselves and allow the usage to spread organically. The very idea of something being "master" anything is just – unlikely.
What we really need is some form of community-outreach/centralization on another platform, probably Discord, if only because it makes it easy to find and share links to content which is appropriate to our interests, but kept in a single silo so that there's one place that we know we can go to for that content type.
Other communities have been doing quite well, and I would probably have already created a Discord server for RPG-folk, but I have been brain-eaten by doing database delving on the steem blockchain, and honestly I have no other excuse.
If there's interest, we can probably make it happen.
Actually, I already have a Discord that I started (mostly) for just this reason. It hasn't taken off at all yet, but...it's there.

Yes, I named it after my former company, but the original hope was I would gain some followers from old stomping grounds.
Then the death-flu/work overtime hit and I haven't been able to get around to it yet.
Yeah, I was wondering if the "master" idea was flawed, but I was at a loss as to what else to do. I fully plan on using it tho, with the hopes that it does grow organically.
As for your database delving, I am glad you are doing it. It is, at the very least, always a solid read and usually answers one question I didn't even know I had yet.
You would be in the very midst of reading a new one if Utopian were not throwing its hands in the air and giving me a dirty look when I try to shove something up there.
Believe me, I'd much rather be writing some RPG content – but I have to go where the whim takes me and, truthfully? Writing stuff which talks about the inner workings of the blockchain and the social architecture around it pays off a lot more than writing any amount of RPG content (that doesn't heavily lean on 3D modeling as well).
Which is true in real life, too, so I suppose some things are expected.
