I was thinking about this game and proably the biggest challenge will be to encourage proper roleplay and not just made up exuses for powergaming. Ive come to the conclusion that the best thing would to be to have the GM in a minor power. Every time someone wants to declare war they should inform the GM of why and reasons. The GM should hold the right to refuse if he feels it is bad roleplay(i wouldnt expect this too often though). I think another potential problem would be people accusing each other of bad roleplay or being powergamers. This could be even worse!
I think the key guideline should be that people set roleplay style objectives for themselves. All out war wasnt common in EU times. Limited expeditions should be more common. Also people should certainly more open with their policies. There werent that many 'pearl harbours' back then. In 99percent of wars the demmands would be made at the start. This is not to say they didnt change at the end. Would be nice to see a lot of activity on the forum. Lots of deals and accusations being made.
