Can anyone point me to a downloadable map of "Impossible" size (320x320) for the Tribes Of The East? I really dislike what's created by the random map generator. I want water and interconnecting roads and more cities.

I think you should be able to find some on Celestial Heavens or MapHaven. You'll have to be very patient, though, AI takes forever on impossible size maps, I gave up after less than a week.

http://www.maps4heroes.com/ has some. Enjoy.

I recently finished making mine and while I was so excited while creating it, I have to admit that I became thoroughly bored playing it. It's so big that it takes forever to cover everything. That and it suffers from horrible lag in the later months.
