Ottoman, Italian, and American territories and units will be represented by neutrals at the beginning. Their territories and units will first be replaced with their respective nations, and they will become playable only in the following round.
Because if Italy only mobilizes and becomes playable in round 3, the Austrian AI would likely leave the Italian front undefended and mess up the balance. Italian units appearing 1 round earlier gives the Austrian AI time to respond.
I agree with the Switzerland issue. It should be defended by at least 6 infantry.
I'm also not sure whether Petersburg or Moscow should be the capital. Germany will have an East Prussia factory, so Moscow would probably be the better capital for gameplay reasons.
