So, last year I did some actual creative writing in a crowdsourced universe I helped build in a text-based wiki-roleplaying game. At the time it was a diversion, a little bit of playing around while I gave my main project a rest (actually that's what it still is). I figured that like anything based out of an online game, it probably wasn't going to go very far. Problem....the writing group freaking loved it. Like several of them tried to talk me into abandoning my main project and focussing on it. That's not going to happen, but I digress... The point is that the world works as a fictional universe REALLY well. And that's potentially bad because the original game, including the parts I wrote, are under a Creative Commons license like everything else on Wikia. So, in theory, I can write in the world all I want and publish content based on it - but since it's copylefted I can't copyRIGHT it. Which could be a problem submitting any stories loosely based in that reality to publications that copyright their material. So, the question then becomes how to handle content that I wrote, but which I wrote as submissions to a copylefted game that I wasn't originally planning to use for actual fiction. How different would I have to make the world before I can plausibly have something pitchable? The high concept would hold water even if I change a bunch of stuff, but certain things would have to stay roughly the same to work properly.
