I just read through again our emails and this thread to check our preference for playing which team. Basically, we are mostly happy with the original setting.
So:
(1) Unassigned: Germany, Hungary, Italy - 3 civ
(2) Fandazma: Japan, Manchuria, Thailand - 3 civ
(3) Ace of Spades: Turkey, Egypt, Arabia, Iraq, Iran - 5 civ
(4) Dazz_G: Russia, Mongolia, Communist China - 3 civ
(5) Genghis_Kai: Nationalist China, France, Netherlands, Greece - 4 civ
(6) Borgg: Britain, South Africa, Australia, New Zealand - 4 civ
(7) Bastian-Bux: Canada, America, Mexico - 3 civ
(8) Adhesive86: Colombia, Peru, Brazil, Argentina, Chile - 5 civ
Neutral states: Finland, Sweden, Norway, Spain, Portugal, Nepal
Martin, would you mind trying the Germany team? I am sure you are more than capable for the biggest aggressor in the game

Then we just need to find one more for the Middle east team, and if we can't find one, just leave it for AI.
If you wish, you can also try the French team, and I can be Germany again.
