...Is there one?
The only AGOED Wiki that I could find seemed to be exclusively about AGEOD's American Civil War game.
On a separate matter, this is a good opportunity to say how pleasantly surprised I am by AJE. While the complexity is rather intimidating, it's fascinating to consider how all of the complexities of supply and weather and cohesion and (what not) come together in an immersive experience to create a simulation that feels genuinely historic. I hope that the developers of this game have been duely recognized for their skill, research, and artistry.
I'm also pleasantly surprised by the civility and helpfulness of the AJE forums. I haven't read all threads, but I have browsed through all 25 pages of the main AJE Forum, reading threads that interested me. Again, I was pleasantly surprised, without a single exception. I was most surprised by the active participation of both the Designer and Lead Programmer. How cool. :)
My opinion in all matters is inconsequential, but for what it's worth: I'm impressed with the game, and its community.
