I must be doing something wrong. I rarely seem to be able to get the AI to buy my maps. I get the "we're not interested" routine. I usually leave the offer blank to start, in order to see if they are interested. Any tips for me?
Haven't had any success with selling maps, I usually give them as gifts to butter them up or include in negotiations to seal the deal. When proposing an alliance, offer map info along with the alliance offer, especially if you are also demanding something. And read Tamur's guide, if you haven't already, as it is superb.

Not to brag, but I'm most likely, the richest guy out of any other RTW player. Yea it has taken out many aspects of the Campaign, but had I not had the cash, I'd lost long ago. Even with the cash, I was loseing the war forever, and this weekdend, at last suddenly broke out of the shell, and in four hours more than quadruppled my Empire! My exact cash is not known to me, but when I start a new Campagin, I'll take out the cash, and play regular, but will have to pick a faction that isnt attacked by four people after the first turn literally.

But the idea of my cash, is like, 19,963,000,000. Somewhere in that range. I didnt care about the money aspect of the game at the start, just getting the cities & armies, to get the gyst of the game down. After I win this Campaign, I'll start a new one, different faction, and regular cash.
What faction are you playing as that you need 10 billion dinarii??? Even the poorest ones can be managed, you just need to spend some time. *Mumbles about what I could do with 10 billion dinarii, mostly involving bribing entire continents* Jeez...
