I' never sell map information. What I do is do a map info for map info and in the beginning any of the A.I. factions will do a map info for map info. If you ever ask the Selucids for map info heres the response that's almost guaranteed. Map info for map info and an alliance. Just avoid the selucid fleets or they'll take you down with them

Also if you wait a while and make your map info unique as in never selling it. Then go to the Egyptians and they'll pay you a nice 25g denaris for your map info. Surprised me a bit I asked trade rights and map info for map info, they replied map info for 25 g's and accept or we will attack........ um ok but after that you wo'nt be able to afford to attack me.

Anyways the only time I try to milk money is in a ceasefire and dangit the comp never accepts.

I looted over 100 grand from Egyptian cities and they wanted me to pay for a ceasefire. So the only thing I could do in return was retrieve former Selucid cities and return them to them. and continue looting the Nile cities as I could not hold onto them playing as the Numidians.
