I've been thinking about developing a diplomatic trait that works as thus: Instead of a 10 turn peace treaty someone with this diplomatic trait gets a 20 turn treaty. This can be broken by the diplomatic leader after ten turns, however it cannot be broken by the affected non-diplomatic leader, so as not to to disadvantage diplomatic leaders. In a diplo leader vs diplo leader situation, the effect is negated, so its back to 10 turns. This trait could also apply to other treaties, gold per turn, defence pacts and so forth. I think this could be a unique trait as I often find myself waiting to buy off strong civs before invading one of their allies. a 20 turn treaty would enable more larger expansion. I have started tinkering with SDK and python but have no formal training, just a strong desire to mod Civ4. What do think of this idea and where should I start my tinkering?
