First, I thought I would make it clear that I was reviewing the product -as one should in a product review- and not reviewing the way Amazon chose to advertise this product.
It appears that one user decided to rate it 1-star, based on Amazon being misleading. Yeah, that works, the fact that Amazon didn't make it clear that there were 2 parts to it automatically renders all information in the book useless, even though they couldn't give a much clearer walkthrough than they did without taking your DS and actually playing the game for you...
Comes with complete maps for the Johto region, Full Pokedex, and where to find everything, a complete walkthrough, character profiles, Pokewalker and Wi-fi guides, move types, and which types they are effective against, and even a recommended route to take. I give this five stars because nothing was missed, and yes, as another naive individual already pointed out, a second guide will be released detailing the Kanto region and the reason that no such guide was featured in the related products is because it has not yet been released!
