I was thinking about that too. I already have it semi-finished as part of my Japan progress. The big question is how many regions it should have. All the originals (that will give me some work) or whatever is present now at the Japan map (less work for me) or the bare minimum (4 or so and work for me).

I am thinking of doing whatever I have now at the Japan map: 80 provinces or so, 2 factions (briton and senate), and descr_strat + map_...tga's that are stripped to the bare minimum.

We would only need to write some guidelines for how to add a faction/province and how to edit the campaignmap.

I guess I will have the files ready tomorrow.
