SaGa 2: Hihou Densetsu - Goddess of Destiny Official Guide Book

This book has most of the game content, including an extensive monster and item appendix. The maps are very well illustrated as well. However, the layout of the guidebook in general is a little cramped in comparison to other guidebooks. However, this is your only choice if you want a guide book for Saga 2.

I suggest that you have a good command of Japanese before buying this product as well.
