The biggest difference is in the nature of the conflicts. The CW was basically a grim fight to the death, while the Napoleonic wars end quickly when one side had beaten up on the other enough and taken enough territory. The losing side can then be offered surrender terms and pay the price of peace before being completely destroyed

.
Also there are 7 major powers who can work together--especially in PBEM--and numerous minor powers which can be manipulated through diplomatic actions

.
The map and units are beautiful, and from size, it dwarfs the CW2 map, or at least if feels that way

.
Turns are 7 days, and the grand campaigns go for 10 years(!!), so there are 4 times as many turns!!
If you've ever dreamed of playing a campaign where the Confederacy has the resources of the North and the leaders of the South vs a North on their own island, but after they've already gotten their best leaders, but with lots of other 'Norths' small and large on the same continent and dozens of different, but much larger Indian nations... well Napoleon is your mega-Lee and this is your game
