I was playing as Greece attempting a Science victory when Suleiman attacks me. No problem since I was way ahead of him in technology, despite him having twice the number of cities (and Japan having about 5x the number of cities). Anyways after about 10 turns of warding off his pathetic army he sues for peace... He tried that at least 4-5 more times before he just proposed a peace - peace deal, which I accepted (needed the army units to fend off the western frontier). Here was his score compared to mine and the others. Has anyone else experienced this odd AI behavior?
