There is an OGL game called For Gold & Glory which is a clone of 2nd Edition AD&D. Since there is no compendium available for AD&D and probably no chance they will ever open that up for us grognards, I am looking into developing FG&G for Roll20 so we can simulate the 2e experience with the bells and whistles that a compendium allows. Is this within Roll20's rules and current functions? How do I go about it and how intense is the work behind a compendium? (no coding experience here, only very light HTML but I have coder friends and this might be a group exercise.)
