The holy man mission seemed impossible, up until that mission I was able to win most of the time during the greek campaign on hardest, with a few exceptions. (so, harder AI would’ve been better).
However no matter what I did it seemed the AI was was ahead of me economy-wise, with ridiculous chariot spam eventually. The way I was finally able to win (took almost four hours) was to wall up the crossing ASAP and use scout ships to block and keep the enemies from crossing, and eventually tower it up so there was no way the enemy could cross over to my lands. Even though he should have been starved out for resources, somehow he seemed to have plenty of gold and wood, it seemed like he must have been cheating. The only way I was able to get gold was to build a bunch of merchant ships and trade with yellow (who I wiped out but left him with a single dock so I could trade). And I had to drop the difficulty down to moderate from hardest. Can anyone confirm that the AI actually cheats? There was no way he could have had any gold, yet he had plenty of priests, lol.
