Rings of Workable Tiles (Cities)

[HardRocker]

Is there a way to change the number of workable tiles around a city?

I mean, is there a way to make it so the city can work, say, 5 rings instead of 3?

I was kinda wondering this for a mod idea, so if anyone knows and can explain it (if it's possible) I would greatly appreciate it.

Well, you could try changing CITY_PLOTS_RADIUS in Defines (it's in the DB but not the .xml file, but probably changeable by SQL; see here). I'd bet a lot that it won't do anything or won't work properly. But give it a try.
