Andre E. said: I'm hoping that at some point I can create a compendium for Roll20, but I saw that Roll20 only allow compendiums that are licensed under OGL. Before considering creating a Roll20 compendium for the game, you'd probably want a character sheet for it first, before considering a compendium(Assuming it functions anything like the majory of ttrpgs or the games that currently have compendiums). Even ignoring the thing about "Creative Commons vs. OGL", it takes effort to create a compendium for Roll20. To my mind, the fact that the existing compendiums on Roll20(free or paid) are mostly just from the larger publishers, is an indication that "compendium creation" for most games developed by independent solo-creators, is currently out of scope when it comes to work/time/costs. Is this the case indefinitely, or will this change at some point in the future? Note: Keith was talking about Custom compendiums, the kind that each user or player could create for themselves and use in their personal games, while I was talking about the official, published compendiums Roll20 currently have, such as the one for D&D5E. So in conclusion, it's likely that a Roll20 compendium for your game is not going to be a possibility in the near future whether we're talking about a published or private compendium, and that is still assuming that the thing about licensing is in your favour. If your game doesn't have a character sheet or you'd want the compendium to work well with one, it's also possible you're getting ahead of yourself, as character sheets aren't an easy thing either.
