The mother of all multiplayer games !!!

Since there already are enough reviews dealing with the single player mode, I would like to clean up the multiplayer game here.
Anticipation is to say: This Nintendo took the cake! Something ingenious yes I have not seen!
You play four (best), equipped with a Gameboy Advance per player and a Gamecube.
The figure on the TV You control principle with the GBA.
In each of the levels, each player has either a map of the area, only the locations of the monsters,
only the positions of the treasures, or only the vulnerabilities of each opponent on his GBA "Radar".
This means that all players must interact violently; (Attention, left a monster, etc.); a crazy fun!
In addition, of course, you have an entire GBA menu in which you can change to select there weapons equipment, magic, character values, etc..
So the other players will not be stopped if someone makes changes to his character.
Of course there's still multi-attacks, which can be run only with more than one character.
The story is quite nice but not huge; But here is certainly the game to pass multi foreground.
CONCLUSION: Four friends with GBA and GC should invest their money in any case in this game and four GBA-GC link cable, then go for RPG fans off the post!
Even for two awesome, but obviously not as funny as four.
Otherwise, probably a bit expensive, since each player needed to play a GBA.
