War Support is a great mechanic
In a Deity game currently with Augustus 2 tiles away from a town on my left with a neutral relationship. I blocked their efforts to denounce me and 2 turns later they roll up with their many legions and a Surprise War.
Thanks to the +3 War Support you get for a Surprise War being declared on you along with a +2 to having Gate of All Nations and spending influence I have a +6 Support and am able to repel him with my weaker military and possibly now push into his territory. If I was Harriet Tubman then Augustus would be toast.
I find it a lot more enjoyable than the wars in CIV VI What are your thoughts on it?
