I would suggest a faction suggestion thread.
As for US... the escale is nearly laughable (no offense). Both armies united dont even make up for the Spanish regular army at the moment, for example. Probably the Swedish army is bigger too. Even the losses at Borodino are already larger than those ones. The Napoleonic Wars were about Napoleon, who focused on Europe.
Oh? and our battles of 250 soldiers equate to large European battles how?
If the game is about Napoleon and not the Napoleonic Wars, why do we see British fighting Russians, Prussians, and Austrians?
What is laughable is the veiled attempt exclude a part of the world that Post-modern Europeans loath with weak game arguments like those above. Like it or not, the war of 1812 was a DIRECT result of the Napoleonic wars.
If you want to exclude a combatant of the Napoleonic Wars simply for Euro-phile reason, just say so.
Truth test, If this community was 50% Spanish would the Spanish Army have been included? I think so.
