This guide was done pretty well, along with having a lot of information in it. It tells you the best ways to get through each stage, and the best way to get DP so you can get the summon stones, and the best items.
It has a complete list of every weapon and item in the game. It tells you about each character and what they get each level(stat wise) and their skills. It gives you a complete list of summons's and a complete list of the pp catalog. Basically what you want to have in this guide, is in their. It's nice to have something like this, when websites like Gamefaq's have outdated guides for the Japanese version. Even then they don't have as much information than this guide has.
The pages are glossy, which i think is nice. I don't like how they did the pages of TES4 and Fallout 3. The cover is soft pages, so no hard covers like fallout 3 or gears of war 2. Most pages have some cool artwork, and photographs on it which is nice to look at.
On the downside it doesn't have every code that the Japanese version of the game has, but thats due to Square Enix waiting to release all the codes and no the guides fault. So far the only other place they have released more codes at is the special site for Dissidia, that only SE members can look at, but you can most likely find these numbered codes on Gamefaq's.
All in all this is a great guide, and i really like what i bought, and its at a great price too compared to Gamestop's price of 19.99 + shipping / tax. So if you like this game, BUY THIS GUIDE.
