How does Civil War II difer from it's predecessor?

[WMitty]

Besides a larger map area (and prettier map), more officers now, etc.,....
-
Does this game play differently than it's predecessor - American Civil War The Blue and the Gray?
Can Battles be managed by choosing tactics now as in Wars of Napoleon - for example?
Do you still have the same control over building forces? expanding infrastructure? political policies enacted? etc as you did in American Civil War The Blue and the Gray?

In short, is Civil War II the same game, just expanded in area, with a prettier map?
Or is it a very different game - with some additions along with things you can no longer do?

Thanks

I'm still playing game and learning the newness of it so I can't say yet. I'll get back in a few weeks.[;)]
