Say you get wiped out, but for some reason you really like the world you “created”. You like how it all turned out and so on. How about an option to start a new company in that same world from scratch? And if you implant gravestones and other persistent stuff like that let it still be on the map as a reminder, for immersion purposes and making the world feel truly alive.
And on that subject. How about a marker on the map where you had great battles/victories, a bit liked Medieval Total War II?
