If the end date is far enough away, we could become the ancient race!
Or maybe there could be a savegame converter "Stellaris end date"->"Stellaris starting date", which takes the old galaxy, destroys some planets/systems here and there, puts some new in, and takes the vast fallen empires from the converted save into account for ruin planets and other stuff. Maybe those savegames could be even transferable, so another player could play in the ruins of my fallen civilization.![]()
This is actually a brilliant idea
