so many campaigns, I'm confused what is what

OKAY I just bought N:TW and I am confused by all teh campaigns. I got all the DLC with it so help me here:

"Napoleon's Campaigns" are all the campaigns where you can play as the French right? I just beat Italy and I'm doing Egypt now. Will the last one, Europe, be very large like E:TW (without the colonies)?

Napoleon's Battles is self explanatory.

Oriental Campaigns ; The opposite of Napoleon's, aka playing as the other factiosn and trying to kill Napoleon's armies?

Peninsular Campaigns ; smaller Spanish conflict?

Sorry I'm such a noob, just overwhelmed.

Just how you said it
Only Oriental campaigns is Campaigns of the Coalition, where you fight as Britain, Prussia, Austria or Russia against the French.

OK thanks. I was sooo confused because I thought the whole game was going to be like the Italy Campaign for a second, and I didn't much enjoy that one... hahaha
