I don't see how 45$ it too much for the size of the game they offer. Also so many classes for characters that can be built differently, and so many races to choose from, and there will not be stupid MMO filler quests.
I am sure main story will also be more interesting than DAI.
They are going for BG size and complexity people, only thing DAI will have over it is better graphics and romances (are those worth extra 15$?). That means if they succeed this is a game that you will be still playing in 10 years, where you will be trying out different party combinations and so on.
I see that as being worth 45$. (EU are worse as it will be 45E) .
I need to be there for that live stream
