I have a game (Year Zero Mini) which I want to encourage other people to use to create their own works. I also have other games in the pipeline which I would want to have the same arrangement.
Under the old OGL, it was pretty easy to understand how derivative works functioned, as essentially each person added their own company information in a "chain" at the end of the license.
However, there is nothing similar in the new FTL and there is nothing to suggest this is intended. So my question is this: would people be allowed people to create (and sell) expansions of FTL games provided they also use the FTL? Or would we (third party publishers of the "base" FTL games) need to create additional terms (or even an additional license) to allow other people to make and sell expansions to our FTL games?
