Here is just a few quick thoughts:

First, lets get the bad over with. 

Negatives: 

-Some performance hitching (I have an i7 920 w/ gtx 285, I shouldn't be having performance issues, but the game with hitch while zooming out, or when combining armies, or at the end of a turn)

-Lack of Documentation/Tutorial (I'm having to figure a lot of things out by trial and error)

-Tactical Battles need some work (camera issues)

Positives: 

-Everything Else!

-Love the art style

-Love the Music

-Love the UI

-Love Designing my Units

Bottom Line:

So far I've barley touched the game by only being 2 hours into the Campaign, but from what I've seen this game is utterly fantastic. A few minor issues here and there, and a severe lack of documentation, but other than that, I love it. 

Thanks Stardock and Frogboy for producing an awesome game!
