Maybe we could have something where Monarch 1 sends a "War Invitation" to Monarch 2. Monarch 2 can accept or decline, and if they accept an automatic CF is put into affect for 24 hours. At the end of the 24 hours war automatically begins. It would be interesting to see how wars would be when both kingdoms are pretty much at full strength and both know exactly when wars start. Could get crazy.
Thoughts?
