This is so entertaining! On one hand we have the roleplaying element, and then on the other the Real-politik..And behind it all, the jostling to position oneself for the next game, and the next after that..wich ultimately will lead to the positions in the final hoi-something game in two? years time..
Russia hasn't needed to attack anyone, their position is just fine for most of the games until HOI..same with Caliphate..Denmark should be ok too, but the rest of the powers could all use several of the following :
prettier borders with less enemies on them ,
and better access to the New World and/or Asia.
What could be good would be some kind of point system, whereby you score VP's at the end of each individual game of the great campaign..I just have no idea how that could work...
