I have played the card game, played the first GBA Yu-Gi-Oh! game, and I am a fan of the TV series. However, Yu-GiOh! Worldwide Edition is really a re-hash of the first GBA game, except with more cards, and more people to "duel." It features the same cards, same system, same graphics, evertyhing is the same. Nothing is improved. The action in this game is fun at first, and collecting cards is very enjoyable, however, there is LITTLE or NO strategy involved in this game, and it is really all about getting and hoarding and playing out the best monsters with the most attack and defense points. This game is really really not worth your money. If you really really want a GBA game with cards, get this game, it is not so bad that it is unplayable. However, if you are willing to get something different, then dont give this game a second glance.
