Thanks for any input, but i'm specifically interested if there is anything that gives a description of all the different scenarios?
There isn't any. But I did a 1792 france guide.
You can still do 23 year campaigns in all other scenario's or even play longer than the scenario default. I know the turn report shows how many turns are left in the game and I think it says what the victory conditions are. I know the balanced scenario has equal armies except sweden and britain are half sized. France spain and britain still have big fleets, but the province production is all different.
In 1792 Austria is king of the hill and france has a lot of internal problems dealing with the french revolution, let alone war with austria and prussia. Whereas in 1805 France is king of the hill.
