Final Fantasy Crystal Chronicles

Once you gain the ability to travel to Mt Kilanda (Year 4) and Leuda/Lynari Desert (Year 5), look out for the items Kilanda Sulfur (Mt Kilanda) and Cactus Flower (Lynari Desert). You can trade these items with Tristan for increasingly valuable discounts.

Once you get a discount, it will apply to the entire caravan, which helps considerably in multiplayer, where you have to pay per head for boat rides.

It's much more convinient to utilize Magic Rings instead of Magicite. You have a fair chance of obtaining one in the Rings' respective level, either from a Treasure Chest or after beating the Boss enemy. They will count as Artifacts/Treasures. They can be found easily by just repeatedly replaying the level, save the Life Ring. You must be on your 3rd try or higher to find it.

The game can only be played on the GBA screens.

In Single Player Mode, whenever you enter a moogle house, Mog is in front of the fireplace. He asks you to paint him. You can make him look neat, but painting Mog has special effects. Whenever Mog says "Hang in there, kupo!" when you are in battle, he'll cast a spell provided you've made him put down the chalice. His color affects whether he'll cast a Fire spell, Blizzard spell, or a Thunder spell:

White/Haircut - Random
Red - Always Fire
Blue - Always Blizzard
Green - Always Thunder

Also, if you use the Game Boy Advance in Single Player Mode, you get the Multiplayer Mode Radar and your Bonus Condition. Mog's color also affects which Radar you get:

White - Map
Red - Monster Radar
Blue - Treasure Chest Radar
Green - Monster Data

Once you visit all 23 moogle houses and collect all 23 stamps, you will no longer need to go to a certain Moogle House to play a specific course. Any moogle house lets you play any of the different Blazin' Caravans tracks.
