Ahhhhh!

Have you all here forgot the roles of the "smaller" countries during the war? A very good example for that, would be that the Swedish kingdom planned several invasions of france, with the help of the British and ofcourse, Russia (Although this was at the beginning of the war). They had some 10.000 british troops and as far as I can remember, even more, russian soldiers, at Pommeria. However, the peace-war making all the time, plus politic facts, prevented the invasion... So they were sent back. Continuously; Austria was never really "knocked out" of the war even though the dramatic loss at Wagram and other battles. But they did likely not have the amount of men after that, and the war didn't really continue in Austria, but at other places (Leipzig etc.) with Austrian soldiers fighting with their Coalition allies. So you could say that, Spain were fighting in their own country and about to win their war with the help of the British, whilst Austria had "lost" somewhat much, forcing them to perhaps more indirectly waging the war in other countries.
So.. whats the most interesting? Adding a winning country or a "losing" one? (No I'm not saying Austria lost against France, they had some nice victories, but their situation was not so favoring themselves).
I don't know. Due me, it would feel more complete with Austria, but at the same time, there is already three of the four major coalition countries, France standing alone.. It'd probably be better adding Spain, and doing so would make France "looking" better. (They would not be a lonely country fighting all of Europe, instead it would show that they had plenty of support).
