Have you played a perfect game? Or is it even possible?
My definition of perfect game (where I fell short in parentheses):
Recruited all the non-generic units.
Level 99 for all units.
Mastered every job class (no one knows Zodiac except for Ramza).
At least one of every item (except Eustacheon II and Javelin II).
Suceeded in every proposition.
Won all the rare treasure (except one).
Explored all the unexplored lands.
Won every Zodiac Stone (I'm missing several).
I think I know how to get my other party members to learn Zodiac.
I blame myself for missing the weapons and treasure. The game's guide is inaccurate about them. Unfortunately, I'm not sure which proposition is the one which I should have won a rare treasure from. I can narrow it down though.
I don't think you get every stone in the game. Perhaps by the end of the last battle.
