Then, Young Lady, maybe you could guide me to something more relevant on this topic?
This one of quite a few posts that should be consolidated into a true guide, the trouble is in a week things may have changed.
The main point of this post is really about the gifting cities exploit, and it is an exploit in my view because you can come out of wars with everyone loving you. Playing GOTM is a really good way of working through it all with others, everyone is helpful to questions but this gifting cities and s an exploit that is banned there.
I do have half a diplomacy guide that lists the things in this thread and many others but how relevant that will be is a good question.
This is a guide purely on the warmongering side of war, there are plenty of other posts and guides that discuss war much better than this, especially science victory ones.
Some things missed out of this
Ghandi’s negative warmonger agenda negative is removed by liberating a civ/CS
Getting a city ceded to you gives you more warmonger points (ceding is broken)
There is no warmonger penalties / war weariness for length of war so you can always declare on everyone as soon as you meet them
The entire way warmonger points work is not discussed here... so declare a joint war in the modern age for 24 warmonger points (unless a civ is also at war or considered an enemy when it is less), you get half this for each city taken. If someone declares a formal or joint war against you and you take one of their cities your warmongering is at surprise levels (they will get -12 for taking a city while you will get -18 for taking one of theirs)- this means his advice to be attacked is a little poor.
How formally declaring a war reduces warmongering
How razing a city gives a permanent -20 that gifting cities does not remove
Nothing about the points in each era, how much the Casus system effects this it’s a fair amount of useful stuff missing amd some questionable advice in amongst some great advice and a fine initial document exposing how to exploit the system.
