Well ideas are nice, but I think you don't have any idea how to make or manage a RPG server. as I see how you made the map you showing in at the screenshots in your thread... that city is VERY bad made...
a RPG city tells a story... a RPG city have to look like a nature way.. not everything straight, modern..., you made everything to bigg.. look to your temple and your Bar... omg.. this seems more like a fun server, there map doesn't make sense, that doesn't have any "RPG FEELING" you use a lot of different styles into one city.
This have nothing to do that you can't map, but with the fact you don't know how to create a RPG server.
Take a detailed look at the REAL map.. maybe after looking to the real map you understand how to make a "RPG-server".
Good luck with your project.
Peace,
