1. It contained several errors that starts with the Animae that hot in the book different from the game.
and Chocobos too, such errors are an absolute no-go!
2. There is no overview of all monsters and especially not just as you would from previously known at the appropriate area maps with the most important information
3. field operations, orders, etc. are not described accordingly I am wrong since seemed like hours through the forest of no return and I have otherwise been difficult to do me in some field operations
4. There are no tips for equipment on emissions and / or the boss battles.
5. There is no index, so you scroll indiscriminately around the area, and is not yet found it.
6. No overview of the trophies in the PS4
In total, I regret to say that have 25 not worth it and I in some situations rather trust well on Google in this book.
Compared with the books of earlier I would have in this really -5 * forgiven, but unfortunately that is not.
I can only each of the book would have as a companion game and not discourage them as a collectible.
The story you also get by without a book. And for the side quests and so it is no good.
I use the books actually getting so I really 100% can play the game and no item on the Map overlook or special quests not kill. But in this case I will probably never reach 100%.
