I dont understand all the hate. I had similar idea 10 years ago, having players start on Goroma/Fibula etc with the quest to save all major cities that have been invaded by monsters. I think, based on the trailer, that it looks nice and I might give it a try this weekend.
Playing on a no-changed rl map is pure trash. If I ever made OT with the rl map - I would delete Darashia,Ank,Edron and all other trash island.
Then take all well-known places from those and hide in the main land so people have to explore.
