Community DLC Games Idea, want opinion

So, a while ago I was in a community theater and we put on plays that would break even largely. Our biggest costs were theater rent, followed by specialist hires (a worker with safety training that did our ropes and high powered electrical stuff). We charged pretty cheap tickets in the context of theater, which given the majority of our actors, costuming and props labour etc. was volunteer.

It got me thinking about games. I realise there is an intense dislike of DLC, particularly AAA companies doing day 1 DLC, but even longer term DLC that could not have been made on the budget of the original game and released like a year later or whatever.

The idea was having a platform for, say, RPG systems that's well coded, slick, bla bla bla, and comes with a few base stories, but after that the majority of development after that is done by something similar to the theater group but indie artists, writers etc. and you buy into a long form RPG (or, idk, subscribe on patreon or whatever). Every month (or whatever), some sub-team releases a new part of their adventure or a new system with a new adventure, and you can keep playing with what characters you had before (if that's what's happening).

Things like the Adventurer's Guild (or whatever the D&D one is, where you register and play each adventure bit once alongside thousands of other players) are a thing, this would wind up be something similar but system agnostic and more tech oriented.

IRL, every time a community theater wants to do a show, they don't rebuild the theater and stuff. It's not "wholly original".

I'd also want the writers/artists to be more connected to their community, hypothetically.

The system would have to have very non-coder friendly tools for writers to pull together systems and make maps and stuff. Dialogue trees may be a bridge too far.
