this all depends on the dificulty im playing, if im playing deity i prioritize growth, and i try and spread my empire out in concentric circles, but that usually doesnt happen.
If im playing on Emperor, i go for OCP mostly and also focus a lot on growth.
Im still experimenting with these two dificulties, so if im playing on a lower dificulty like monarch, each of my citties is placed somewhere for a different reason, not sticking ot one thing and often for lots of things at once.
so i must say growth, as on the higher difficulties, quick growth is really important, or else ull fall behind too quickly.
