Completion bonus
Successfully complete the game and save when prompted. Start a new game and select the cleared saved game file. You will begin with the money from your previous game, collected formations, your Party SP, collected Epics, inventory and storage items, and your Hero's name. Additionally, press L2 or Triangle to run faster.
Easy money and armor
Once you recruit Subala, store all of your party items with Chuck. Then, play the fishing game against Subala at your headquarters. When you play the fishing game, sometimes you will catch "? Pot" and parts of fish bodies. Play the fishing game about five or six times (depending upon your skill). Go to the closest appraiser and get all of your "? Pots" appraised. You can then turn around and sell the pots to the appraiser for a significant profit. It is possible to make over 200,000 Potch in one trip. The fish body parts are armor that you can equip on a few characters. This is good armor to have fairly early in the game.
