Easy Mode

Easy mode is unlocked after completing the main game in Golden Sun: The Lost Age (interestingly, it isn't available in the original Golden Sun). When starting a new file you will be asked to choose a game mode. With easy mode you start at the level your Adepts were at the end of the main game. All enemies will retain their original stats as well. It also transfers all your money and EXP from the completed file to the new game. It does not transfer items or Djinn, however.

It should be noted that your characters will not have the same Psynergy when you start a game in Easy Mode. For example, Jenna starts off with her Flare and Fume Psynergies. This is only temporary, however, and once you obtain Echo all your Psynergies will be returned.
