I had one another problem where AIs have tons of gold with 10 cities, what, they are only sitting on trading posts(prince difficulty which I have already beaten, but still

)? I mean, Rome has around 60 gpt somewhere around renessaince area and he has musketeers as I and I had a tech lead and I can't understand it.
Ok. I played your save game for a few turns until wife aggro commenced around turn 422 due to other weekend plans. Initially, when loading your save, Rome has 25 GPT, England has 60 GPT and I think those are the two strongest.
First, you have tons of resources, sell them to the AI. You don't need extra luxuries, you don't even need all your iron because you hardly have any units that require iron. I kept selling them to the AI for GPT and extra gold and it pushed my gpt up to between 40 and 60 too (along with some other things I did). Meanwhile, the AI's GPT kept fluctuating, they were probably doing the same thing and numbers are changing as trades end and new ones are made.
I mean, where he gets all the food, he's not allied with any maritime city state and has no caravels to find the other continent.
I don't think his civ is so large. From those few turns I can't tell if he's cheating, but it doesn't look *too* abnormal.
I still have a tech lead, but there's soomth strange in this round, maybe I should invest more on trading posts and less on farms and science or what?
If you are trying to make money, there are some oversights. For example, you have one city set to produce wealth, which is very inefficient in this game, but all your cities are set to default focus. Setting them to gold focus would help your gpt. I set the production cities to production focus and those that had little hammers to gold for my handful of turns, and both helped a lot.
Also, you have all those workers. I disbanded all of them. Your biggest problem right now is Rome and Rome has tons of workers, so you'll get new ones soon. (Heh heh.)
In my other prince games, AI was really stupid.
It's not too intelligent in this one either. None of the AIs has any hopes of winning this game anytime soon apart from a score victory.
For that matter, you have about three hundred turns left, so at least a score victory should be possible for you, too. I don't have enough experience with epic games so I don't know how likely it is that you can win one of the other victories. With domination being easier here than before, I wouldn't rule it out.
Regardless, as I said, the biggest problem is Rome. He doesn't have that large an army. With all the extra gold I bought a crossbowman, and later another one. Between these, your great general, your alliance with Monaco, and your existing army, I had no trouble taking Ravenna and that other city next to Monaco (puppet them, of course). After that, he almost stopped sending more units. It'll also gain you the allegiance of that other city state on the west coast of your continent who asked you to weaken Rome. So I definitely think you have a realistic chance if you can take out Rome.
Regarding science, you could probably improve a lot, but adding more cities even if they're only former Roman puppet cities, should help too.
Oh and I cancelled the war with Liz since you have no hopes of doing anything there, and it would probably end up making either her or Hiawatha stronger, which you don't want. But I don't know, it could work if you just declare on her and just sit there.
