If you are curious how they handle the setup, in simplest terms it works like this:
Napoleon can choose how large a force he wants to bring on. Regardless of what he chooses, all HQs begin on the map. If he goes all in, he must win decisively, if he brings minimal forces, the Coalition must win decisively.
This means, as the Coalition player, you must attack aggressively from the outset to win. If you discover Napoleon has gone all in, you need to switch to the defensive; the sooner, the better!
The fog in the morning doesn’t help!
As soon as I get my copy I’ll be doing some replay videos. We can all laugh at my first feeble attempts to master the field!
