So i started a game on Emperor difficulty (usually play King) and i was Persia and i had Alex as one of my AIs. He was allied with all 16 cs by turn 200.. Is the only way to stop that guy is going to war with him? I retired at this point, as i was pretty sure he was going to diplo win. The game was on small islands and i didn't have the ability to take him out at this point, but i'm looking for advice for future reference.
