What I mean is, all the TW campaigns set unrealistic victory conditions for factions, even when playing "historical".
Just to give one example, as an Austrian I have to break virtually every natural alliance against the main enemy Napoleon to fulfil the winning conditions. I also have to break peace with the Osmanic empire to capture the Balkans, which is highly unrealistic for the period in question.
Same goes for every other faction. I had one game where I had the Russians all over the place, setting up shop in Germany and Switzerland of all places. I had the Spanish land in Croatia and I had Switzerland getting expansive.
