I suppose I didn't lose much by leaving the FFIX guide in the cafeteria at school shortly after I got the game. Even back then my friends and I were discussing how crappy the quality was even compared to the previous Brady Guides. If I recall there were parts in the guide that went something like, "If you really want all of the best secrets, go to Playonline.com". It was quite stupid to not include all content and ask kids to go online to get what they paid for before the internet was quite as universal as it was a few years later.
SaGa Frontier's guide was pretty terrible as well if you consider just how in depth that game was. Although without it I know I had no idea what to do my first attempt to play it.
