I like this idea. Here's my all time hottest start so far:
798482560
798482785
Huge inland sea (legendary, wet, abundant) - start as Saladin with 5 AI players.
You end up starting next to a line of three spice and there is lots of other stuff nearby. You start close to the coast, on the west edge of the sea.
What should the format for map seed descriptions be?
Also - has anyone figured out how to "swap" in with another civ in the same location? Is that possible? If so, how? I tried selecting the Germans... but ended up on the opposite edge of the map, and in a different place entirely when I set the AI players to distinct powers instead of just the usual random assortment.
