I really enjoyed this book, even though I felt some important subjects were left out, but I guess it's impossible to include analysis from every single aspect of a universe and games as complex and rich as Taro's.
So, first than anything, this is a book about Yoko Taro. So I'm guessing all readers interested are fans or at least know who he is and played his games, otherwise any attempt to read it will be meaningless as you will have no idea what it's talking about. It's very, very specific. Second thing to consider, in case you saw the cover and got the wrong idea, it's not an art book, it's a long essay that focuses on the Japanese gaming industry at the time of Taro's first game and it's evolution, tells the backstory of the birth and production of each one of his games until Automata and then reflects on the themes central to each of them and the evolvement of Taro's views using psychology and philosophy.
A considerable part of the book recounts the events of every game in some detail, so that might be a bit reiterative if you played any of those too many times or too recently. I played the Replicant remake just a couple of months ago and was still quite interested in recollecting it, so it depends on each reader. The book has also lots of tiny details, anecdotes and quotes from interviews, which is really interesting, besides a lovely foreword by Taro himself, which is perfect.
So, I really admire Taro's work and adore every tiny detail of his universe. I love the depth and the questioning, the philosophical agony and trauma, but also, specially in Automata, the kindness and hope you can glimpse barely visible between all the devastation and meaninglessness. And this book made me realize some details I hadn't noticed before (And I always get Platinum so play extensively), which was awesome. For example, I remember in Automata while playing in the factory during the cult's descent to madness, I thought it was quite ironic that the dead leader was named after Kierkegaard. I should've known it wasn't an ironic coincidence, as in Automata everything tells something directly related to the plot and reflects on something about it, there's no meaningless side quest, character or dialogue, as in Replicant (in which a lot of side quests are just for farming) It turns out every arc related to a philosopher is based on or questions their main ideas, totally destroying them. Also, I remember during route B after a series of very dark side quests it hit me suddenly how it was all very morbid, everything ended in death or meaninglessness, I think it must have been because I did in consecutive order the wise machines, the last stage of father Servo, Engels death and the E model or something like that, and then looking back I realized it had always been like that just that I didn't notice among all the other details, from the first apparently meaningless ones such as getting the materials for the arms and items dealers at the Resistance camp. Still, I didn't realize until reading this book, that actually it was I (the player) who ended up stealing the purpose, the meaning of existence for npcs such as father Servo or the speed machine causing their suicide, damn! And what for? Just to get 100% and some reward. I could've just walked away after some of the fights and leave it at that, Servo would've gone on striving to be the strongest. Made me think of the awfully traumatic journey to get every ending and doing things that really broke my heart, like killing everyone at Pascal's during the first visit even though they wave the white flags or abandoning 9S after killing Adam, and how it was a bit less painful after every time I was forced to do something like that because you start to disconnect to it, become numb somehow, like it happens everyday with all the pain and agony we see all over the place, in the news, the streets, etc. Digressing, I'm totally digressing here.
Anyway, this is a must for anyone who likes Taro's works. It reflects on all the big themes present on his games and related content (novels, short stories, concerts, etc), identity, violence, agency, death, meaninglessness, resistance, etc. I felt some subjects that seem really relevant were barely brushed over, but it's still a really satisfying read.
