might sound like a stupid question...but i want to know

[umanwizard]

what is this OCP (optimal city placement) I keep hearing about? What is it, how do you do it, and how effective is it?

IIRC, it is placing cities so that there is no overlap of city tiles - each city gets use of its 21 tile radius. One problem with it is that you waste alot of workable land. Even when your city is size 12, you are only working 12 out of 21 tiles.

Edit: you should try to be more descriptive with your thread titles.
