I ran into something interesting in my last game as Sumeria. I shared the northern half of my home continent with Rome, China and Greece. After an apocalyptic battle between their respective UUs, Mao vassalised Augustus and the map looked a bit like this: CCCCCC CCCCCC RRGGGG RRGGGG SSSSSS SSSSSS Next, Mao declared war on me. His vassal was wiped out in 10 turns or so, and I managed to conquer China itself as well although that was a long and costly process. Realising I'd probably achieve Domination if I conquered Greece (advanced but lacking some key military techs), I went for it, attacking from three directions at once. Pericles never did anything. His stack kept moving about, apparently unsure where to defend, and not even trying a counterattack as I've seen the AI do before if defense is doomed. In the end, I wiped him out with 2/3 of his forces never having seen battle. Is this normal, is this dependent on the leader... and could this be reproduced? This would definitely make me rethink my strategies (war allies might become more useful even if they don't actually do anything themselves...) If anyone has experienced something similar, I would like to hear some comments.
