I do not like an only Pacific SC, and another Only Europe is so double, Just go global with SC 2!
I would also have an option in it where you can decide with you opponent, weather you play allies/axis with total control, or just one plays England, the other Germany, with the other allies/axis controlled by computer, or maybe another player if possible.
Further more it should not be able to teletransport your units from the Urals to the French coach in one turn. That should be limited to a maximum distance per turn.
