These ratings were made as a Sample without too much research. Since we´re(I presume) not really aiming for a classical mafia game I´m not sure how useful the U.N. would be. Most likely the Nations with vetopowers would always block eachother...

This is not realy a mafia game so there wont realy be any special roles as such. Each player will be able to carry out espionage and sabotage each phase as well as attack other countries if so wished.

Heres a list of the only things you will need to realy keep track of.

1. The amount of military you have to swing around.
2. How quickly you can replenish any lost troops.
3. How effective you home guard is. (IE what bonus do you ge from militia when fighting at home)
4. How dependant on oil you are (and how much of a penalty you will recieve if your deprived of it).
5. How effective your secret services are .

An example of this would be that UK has less millitary resources than USSR but have a 25% bonus in espionage and sabotage and suffer less when deprived of oil..
