This is by FAR the best RPG on the GBA that I've ever even heard of! The chracters are engaging, the plot is interesting and has just enough twists to surprise you but not totally lose you, and the graphics and sounds are unparalleled to any other GBA game at the time. I first got it about 2 months after it came out, and yet I still find myself playing it again for the umpteenth time! If you haven't played this game yet, you are missing a really good game!
People you really need to but this game. The story is really good and it will always let you take a different direction and realize that you are going the wrong way. There is enough skill to be involved so you don't have to just attack attack attack. The puzzles will keep you locked in for hours and when you finally get out you will be like wow.
Pros- -Everything -Puzzles -The attacking system is good -Not to easy but not to hard -Very entertaining -You will find yourself playing the game over and over just to find everything
Summary- -All in all the best game in the world. I would recommend buying it and also buying Golden Sun: The Lost Age. They are both probably the best games i have ever played and will keep you entertained for hours upon hours of playing time. I would also recommend buying the strategy guide because otherwise it will take you a VERY long time to beat the game.
