Even with Shogun 2 and Rome 2 being superior for me I still think napoleon stacks up against all Total War games. I sure would love to see a new high budget game!
Here are my hopes for Napoleon 2:
-Expanded campaign map that include all of North Africa, the Middle East, Anatolia and perhaps even India?
-More Island settlements in the Mediterranean.
-More mainland settlements in areas that were previously fairly empty. Such as Paris, Madrid and Russia. There could have easily been 3 or 4 smaller provinces around those Settlements.
-In Napoleon, it takes till later in the game with more techs to upgrade your trade ports to max level; and even then you only get 2 building slots to put out trade ships. Perhaps make unit producing buildings expandable as well as upgrade-able? Example: why not be able to add building slots to barracks or shipyards by being able to expand the barracks or ship yards themselves, and upgrading them to produce better units?
-Skill trees for Agents and Generals.
-More Buildings Resources and Agriculture.
-The ability for an army to build forts on the campaign map that they can winter in and fight out of in Battles.
-More City defenses and siege warfare. In Napoleon pretty much all battles were essentially field battles.
-More playable factions and unique units to each faction.
-Unique agents for factions.
-The ability to field at least 2 full stacks in a battle like Shogun 2 and Rome 2, maybe even 3 full stacks?
-The ability for navies to bombard coastal settlements.
