The game is ready for pretenders. The average number of provinces/player is higher than I had in mind but I'm inclined to go with
Plane of Rusty Nails for a map because Calahan recently created a version with 10 fixed land starts and 1 water start. Since we are all land nations the water start should just be ignored.
You can find the map (and elmokki's other maps)
here. Note that Calahan didn't post the .map file so the starts would be a surprise so when you download the map you won't see those start locations.
