Not really. I think AI's first priority is to build ships. Tons upon tons upon tons of ships. In one of my games India had more than 70 transport ships,probably more than all other units combined. That is insane. In another game Incas built a bunch of galleys and triremes in a closed lake. Later on,some civ(I don't remember who)declared war on them and conquered them. If they built archers,skirmishers and other land units instead of dozens of useless ships they could have won the war.
