Be careful with this as it may lead to play balance problems if you let the choices wide open.I am undecided about enforcing WIF FE 'suggestions?' for which major powers each player controls in team games. For example, with two Axis players does one of them have to play Germany while the other one plays Italy and Japan? Or should this is wide open (my choice). If it is going to be wide open, then why impose the restriction on the players at all? Or even mention it when starting a new game? Perhaps it is just a "note to the players" somewhere?
There is out there a kind of players, that I call the "conventions players", who do not hesitate when given the opportunity to play Italy & Germany, for example, to have a completely ahistorical way of playing the game, only seeking performance & optimization, which can be seen as a spoil of the game to other players (me for example) who prefer the WWII WiF experience & ambiance.
