Just finished the book. It was a fast, easy read.
I have to say, though, the editor needs to be fired. The book was rife with spelling and grammatical errors. I couldn't even keep up with how many variations there were on Reggie Fils-Aimé's name. On top of that there were several fact-checking errors.
I also didn't care for Ryan's smug, smartest-guy-in-the-room tone. The similes and metaphors were laughable at times. And the text is flooded with words that do little else than attempt to prove how smart the author is. Brobdingnagian? I mean c'mon.
That said, it was a fun read at times. I picked up a few things I didn't know, especially about specific games. I did like the passages that explored the psychological side of things (though I assume some/a lot of it is the author's personal take). Overall, though, there wasn't a ton of new info for even casual Nintendo fans.
@Reed RothchilddRothchildRothchilddRot (I don't know why his name is formatted that way; I can't delete it on mobile) hit the nail on the head that the book was general in scope. There's just too little on too much.
It was funny, too. Almost all of Ryan's predictions were completely off-base in terms of Nintendo's future (the book was written in 2011/12).
