frist of all, this is a guide book. Guide book means every ship shows up, but no one drills into details. This books only has a few ship got more than one shoot. Also, it's basiclly a repeat of previous 3dcg books. If you already have most of them, it won't be necessay to buy again. My opinion about the whole 3dcg series is this, only those ones focus on single ship, provide detail look. That way it gives the ship a back to life feeling. If it's about a battle, a task force, all a general introduction of IJN, I would say not worth the money.
