Why AI resign is random ? Sometime it resign very fast then you attack it don't need even lost all TC or villagers. Other time it not resign until not lost all TC and villagers. Today played vs AI that not resign even after lost all villager and TC I need destroy every building before it resign. I play vs Hardest AI and it's resign very random as well difficulty is not feels same even it's set Hardest every time. Sometime AI become very aggressive while other time feels like play vs moderate AI even it's set to hardest. I had match 2 vs 2 and one AI resign just after lost few building and other not gave up until lost all TC and villager.
