Excellent work but ...

Warning intrinsically this book is fabulous probably one of the best on video games ....
Complete and well-written biography of a genius video game which we owe the Game and Watch and especially the game boy .... this is a real bible that explains the policy of Nintendo for many years and since 2002 with the return to the "real game console" (Wii, DS Lite, wii u ...) ...
not to mention the stories and other surprises
However, for me that has Nintendo volume history 1,2 and 3 and the bible game boy unfortunately I have not learned much and I found many things already known and discussed in other books ...
