In Final Fantasy VII, one of the final things you do is to go in the Northern Crater. During it, you have a few points where you are forced to split your team up. Those who go with the main party and those who do not.
When you get to the bottom of the crater, you find a room with all the party members in and sometimes the ones who were not with the main group have an item for you. Does this change depending on the character and the direction they took? Is there an optimal route to send people to gain the better quality items or it it just luck? Does anything else affect which items the other party members pick up?
