Finished this on Olympian. Was very tough, close to impossible.
Halfway the game Hector attacks the city. You need marble to call him, but there is no import source. First you need to conquer a city to get a tribute, but you don't know which one. Later on the shortage of wood is terrible. There is also a lack of fleece, but it's playable with little fleece.
Opponents have big armies.
I like the tributaries

Interesting map. Varied, but enough space for a large city.
Additional Comments: Very tough campaign. Possible on Olympian, but prepare to share your city with Hector for 10 long years.
