modding the Creation Engine is possible because it is based on the Gamebryo Engine. but modders and players are fed up with the buggy mess that the Creation Engine is. there have been statements from Bethesda that they haven't started development on TES VI yet, which makes me wonder whether they are looking for a new game engine for TES VI and FO5. if that is the case, will mods be possible at all for future TES and FO games? I doubt they would stop using a derivative of Gamebyro, because their team has been using the gamebyro, and creation engine for years. Why put money into something that your employees would have to relearn.
