Nice. I was at my cousin's house yesterday, and he showed me his old strategy guide. It's missing the cover and is a bit ratty, but it's otherwise still pretty useful. IIRC, it takes you up to the fire fiend and the airship, and leaves the rest to you.
Sadly, it's full of bad information, because they didn't know about all the bugs. For example, they talk about RUN using the character's AGILITY, except that's only partially true. The variables point to the wrong place. So, person 1 uses 3's AGILITY, person 2 uses 4's, and 3 and 4 each point at something completely unrealated. So, if you have a thief in your group, never put him in slot 1 or 2.
