cultural takeover

[narmox]

how does it work? At chieftain it was easy enough... but now at warlord, the AI builds a bunch of cities and doesn't build anything cultural in them for centuries while I rushbuy temples, libraries, courthouses, colosseums and marketplaces. yet they never switch, while this other city that's farther than these, with more culture than my nearby cities, suddenly switches over (it was farther from my capital than the other ones too)!
