Its an idea.
I got a better one. Read.
Same as the above, but instead of controlling an faction on a gigantic map u could make the map even more gigantic and for example in Holland u can play as Holland, Friesland, Utrecht, Gelre and Zeeland while in Germany u can play as any one of the provinces in there, both of those examples controlled by yourself with your own faction name and banner. I think is better in terms of the amount of players who actually gonna play this.
Which brings me to another idea. What if this "Total War Online" would be an game on its own crossing diffrent era's of history, like on one server you play in the Ancient Age(romans, greeks and carthaginians, u know the deal) while in another server you play in the Gunpowder Age with simple Hand Gonne's and very early matchlock Arquebusiers. It would be limited like this: Prehistoric Age - Englightenment Age(Napoleonic Age as you could call it).
In any case, the 2nd line of the 2nd idea is a must cuz it would make Empire:Total War or any other Total War game way to big.
