@Dave Allen,
"The army is a projectile fired by the British navy." Which interestingly enough, I usually play like this when I play the British campaign in any case.
Which I wonder if you take on the tactics of the particular side you are playing when you are playing the game. For instance, when I play as Britain, I am immediately drawn to Greece, Portugal, and the German lowlands just as the British were. When I play a tactical battle, I almost always use longer lined linear formations, light artillery, and un-concentrated cavalry. But then when I play the French, I always focus on the German lowlands and avoid Russia. And when I play a tactical battle, I always use massed heavy artillery (Napoleons dearest quote as far as I am concerned was "
with cannon, wars are made"), massed cavalry, short dense columns of fusiliers, and heavy screens of voltigeurs as Napoleon had.
Honestly, what better way to really put into practice what you learn about military history than to play it out yourself. I think that's what I find the funnest part of the game. I don't really get into the economics part of the game (I use the art money trainer) more than the historical substance in tactics and so on.
