I am not sure if this would be a feature request or something else.

I am looking for a way to control the city generation within X radius from the world spawn point. What I am wanting to do is have the players spawn in and have no cities or anything within 500 blocks. This allows them to build a starting place as they want and then go out to find the cities.

If there is already a way to control this please let me know. I really like the mod.
