FFVI Worlds Collide

For the prices, may I suggest that if randomized shops is chosen, then prices are given to every item in the game according to their rarity. They did that in Free Entreprise. So, there wouldn't be items that sell for 2 GP in shops, even with "Normal" prices. Also, randomized prices don't have to be a flat randomization, you could choose some formulas that makes the prices gravitate towards certain values (perhaps their "Normal" prices).

Also, it appears that Rare Items have been removed from the game. Do you intend to put them back so that the game becomes kind of a fetch quest, a la Free Entreprise? And if you're worried that there are not enough Rare Items to make it interesting, I have a couple of ideas! The Rare Items could be shuffled along with the other rewards.
