I want to know which kingdom is the most talented. In order to do such, I need to eliminate as many variables as possible.
Same kingdom size, same race and personality combinations, same stipulations regarding ceasefires and diplomacy. Pick your goal, whether it be #1 in land, #1 warring, or just a good old fashioned one versus one war, that's how you determine which kingdom is the most talented. At this point its all about strategy, the strength of the individuals and the strength of the kingdom.
