Unity 3 Blueprints is exactly what it says it is: a guide.
Comments like "this isnt for the serious indie developer", and grading the book poorly are based on personal expectations and, in my opinion of course, unfair in this case. Even "serious" people have to start somewhere and if they'd rather buy a guide than dig up and organize the assortment of free ones out there this is a good place to start!
My personal experience with Blueprints:
1. I've become more comfortable with Unity over time without inundation.
2. I've taken that comfort and started to run with it into expansions of their projects; Like making changes to their "marble madness" game to the point of losing hours of time tweaking extras I've imagined. This alone says their instruction worked as designed.
3. The authors will answer questions! Writing a book isnt signing up for a support job but the company attached here is very friendly and willing to support their readers.
Essentially, as stated before, it did exactly what I asked of it: give me a friendly kick into the world of Unity. (and save me the time of gathering random tutorials!) Thanks deeppixel.com folks!
