Love the idea!!Okawoa said:Perhaps you could bribe cities to open the gates? Or use a spy to...? The chance to open is determined by positive or neg traits.
Pos: Same culture, same religion, high paid, revolt risk high
Neg: Dif culture, dif religion,
And to add to the pos chances, Nationalism! IF a prov has just been captured by an invader, by rebels, or if you are recapturing your land lost in a previous war, the chance of getting the gates opened should be higher!
