Streamline the gameplay tremendously. It's a clusterforget of menus and dialogs and every server is different and there are a million different jobs and abilities and tools with no clear purpose.
Why do you have City RP? To let people own property and encourage them to build cool stuff and come back to your server.
So focus on those things and make them super easy and automatic. Make it easy to get started, and rewarding to build cool stuff.
If you stack stuff onto stuff, you just get a big pile of stuff. But one piece of gold is worth a lot.
