I took a quick look at the official FF XII Guide at Gamestop

[Yar]

Im not surprised the guide is so fat, the game is massive, I have barely touched the side-quests, extra bosses etc.

Still, only losers buy the strategy guides, who likes being told what to do
in a game ? I sure dont.

And others, like myself, use it after we do a first run or when we get stuck. With the LE Book, you buy it now, or never.
