So, I didn't really feel that an exploit was something that HAWTwired readers wanted on thier news feed, but Carlos talked me into it, so blame him if you want someone to blame.

In Chapter Seven, in the city of Palumpolom, at one point you reach Hope's house.  Shorltly after, the militray attacks, and you're engaged into some battles within the domicile.  The house is basically shaped like a loop, and inside are two enemy groups, two item chests, a Save Point, and an Activation Point.

The enemy groups both regularly drop Incentive Chips, a component item that has a selling value of 2,500 gil (I got the drop roughly 3 out of 5 battles).  Kill the enemies, run the loop, and the enemies will respawn as soon as you break line-of-sight with their spawn point.  Kill them again, bag Incentive Chips, and repeat. The scene doesn't end until you use the Activation Point, so as long as you just don't click "Okay" there, you can farm it until you're tired of it.

You can use the shops at the Save Point and sell the Incentive Chips for a buttload of cred (not metric buttload, because this is America), and turn that money around to buy components to upgrade your weapons and accessories to max level.  I only spent a half-hour farming, and I had enough money to upgrade all of my battle party's accessories to Star Level, as well as gaining some good levels on my weapons.  I'm sure someone out there has patience enough to farm out the loop until their entire inventory is starred-out, so have fun.
