How possible would it be to have this built in a way that would allow story progression across one save for the original stories, such as you must complete SoC final quest before Clear Sky quests would become available and so on? Or possibly have it so that once you have completed a save with SoC story you are prompted to start the next story or choose another faction to begin the story of them instead in which case you would still be able to access all of your aquired gear?
