Is D3 worth the $55 upgrade from D2?

[Nethog]

I played Dominions 2 five or six years ago and have just recently begin to play again, and I am actually enjoying the game now more then I remember then before. I did download the Dominions 3 demo and my impression of the game is, yes there is new music and some minor but very nice user interface changes, but it really feels like the same game as Dominions 2. When I looked at the price for D3 I was a little shocked at the $55 price for a game that has been out for almost 5 years. I *would* pay the price if I saw a lot of new content in D3 but to me it felt more like content I would get with a D2 patch. Or if the price was say $30 I would pick it up right away. Am I missing something or is there more to D3 then meets the eye?
