Music can make a huge difference in the feel, fun and professionalism of a game. Simply for adding that goal doesn't mean that development of other parts will have to suffer.
Also keep in mind that this Kickstarter is not what they hope to make. It simply is so that they can develop it enough to possibly pitch it to get more funding. 2 mil. is really not a whole lot when you talk about a few people working full time.
It can, and I'm as pleased about the orchestra as anyone. I'm just saying I'm satisfied with them adding it at 2 mil and forgoing it at 900k. Even then they mentioned the soundtrack as a clear priority. Just because it was going to be non-orchestral doesn't mean it was going to suck.
And yeah ideally every game would have the 100 million budget of a AAA title, but that's like saying "keep in mind that everyone wants a Lamborghini". Assuming this is a success, of course they'll put in their pitch resume. Who wouldn't? But that doesn't mean they don't want to make this game or feel dispassionate about it. Quite the opposite, given that the common theme in many of these kickstarter games is despair at getting any funding at all from the big publishers. Brian Fargo himself has specifically stated he hopes he never has to work with a publisher again.
And so long as they do a good job, I certainly wouldn't mind them using this as a stepping stone. If these kickstarter games can prove a viable market for genres many publishers deem dead, and get higher-level funding for such games, that'd be awesome. Even if they don't, we could be seeing the start of a trend. As these kickstarter games get more and more attention, that draws more and more backers. Hell the OUYA got close to 10 million, in a year or two I don't see why popular games shouldn't follow suit.
