Interviews are such a pain to read and include so many unnecessary, almost annoying things, that I was really struggling to continue reading. I paid money for the interviews with the developer and was hoping to read nice book about development, not things around it. Instead I got a mess: and not only visual side but, what is much more worse, content mess.
Book is full of weird statements & forced questions, each interview feels like if two people were locked in the room and were asked to talk about something which they don't really care about now but they have to still do it. Are you a kid trying to write something or adult writing serious book? Why the hell didn't the author take a small effort to be professional and really prepare instead of shooting questions based on what he is currently thinking about, furniture next to the developer, or what lies on the table in the room? There's no concept, everything is written so randomly and in an annoying style! Almost like the author wants to patronize his readers by pretending not to know anything about game dev and asking for any stupid thing he thinks of. Writing is at a middle school entry-level; it hurts your eyes and brain the more you try to read, and you want to be over with it ASAP and do something else.
Avoid, not worth of your time even if given for free. Yes, not guilty pleasure bad, just plain bad. I think there are better books from other authors, or read some nice short & focused interviews on internet.
