This is my first time through CivIII, having played both CivI and CivII previously.
I did not install the patch before my current game, so I don't know how that affects corruption/waste.
When I changed government from Monarchy to Republic, I saw no change in corruption/waste. I changed again from Republic to Democracy, again no change in corruption/waste. In fact, there were also no changes to the amount of trade/shields produced in my cities, and there was no change to the happy/unhappy people.
In CivII, when you chagned government, you got unhappy people because of military units not being in cities. You also got a *huge* reduction in the ammount of corruption/waste under democracy, regardless of the distance of a city from the capital.
What has changed? Is there some bug? Do I have to start a new game since applying the patch?
Thanks
