If you like endless adventure, minigames, jrpg elements, casually grinding through the adventure and making some pictures, inventions, doing some puzzles around town, building towns (yes even that), or slaying on your mecha, golf, carrying over your items by turning them into items fused into your future items becomes so you never have to mourn losing that cool item and feel like it's all part of your ongoing character development...I could go on...but if that won't sell it nothing will. Oh right, you can catch, train and race fish...and...and... xD This game has SO MUCH!!!
What it does not have, is a satisfactory explanation to a few rare crashes, which can be a pain in a grind game with save points. Look them up if you run into repeat crashes (one is caused by a piece of Max gear).
