I voted Tonberries but thinking of a Moogle game, we should get a game where you play as Stilzkin. (from FFIX)

It's like the game the Freelance Astronauts proposed based around The Merchant from RE4. It's a GTA clone where you have to buy items/weapons somewhere and then travel to some war-torn area to sell them to adventurers.

Also you gotta make sure you're not shot in the face randomly by the person you're peddling your wears to.
