I've been playing Civ 4 for two days now, but I still can't completely understand the new city maintenance, corruption, and unit upkeep system. Does anyone know the details about them?

Thanks.

First WRONG FORUM (General Discussions or Strategy+Tips)

The basic rule is there is not corruption like there was in Civs 1-3 (where your city doesn't produce) However each city (and unit)takes a certain amount of money away from your imperial treasury. For a city the amount of money that it costs your empire to keep depends on
1. How many cities you have
2. How far that particular city is from your capital or Forbidden palace
3. If that city has a courthouse / Police station in it or not

units work under a similar system, but I'm not sure of all those rules myself.

Yeah, I was about to say that this was in the wrong forum. Unfortunately, I don't have the game yet and won't know for a while.
