If you were Manager of Graal2001, what would you do with it? Pretend you are making all the important decisions and coordinating development and assigning jobs to people. How would you manage it?
The first thing I would do is get the players' opinions so that I could a playerworld that suits them. Another thing I would do is most likely edit a lot of the overworld, but not change it. I would just make it appear to be aged or a feeling of landscape movement.
