Now I ask myself, if that's true. Reading those two great AAR's by Narwhal and loki in the Paradox Forum and winning one game as Prussia because of AI stupidity might have given me a wrong pricture, though. I have to admit, that in the beginning I also felt that Austria with it's sheer numbers would be the clear favorite, also in an PBEM (I already bet, that baris would win the PBEM against Narwhahl: :bonk

Prussia not only has the better troops and the much better generals, but it also has the advantage of being able to concentrate its forces while Austrias forces are completely split.
Austria also has to attack. Prussia leads in victory points right from the start. Only taking Königsberg and Wesel will not suffice for Austria. Even less if one considers that prussia will most likely win more battles than Austria thus gaining even more VP's. Last but not least, Prussia gets much more events that raise her national morale. Austria has to struggle to keep the morale just above 90.
That's the reason why I start to think that Prussia is the real favorite, even in an PBEM. What do you think? Am I wrong? What do those people who already played some PBEM's say: Were there more Austrian or more Prussian victories? And what do experienced players say?
