4 The new ultimate expert edition?Paul3065 | 08/05/2007 | See all Paul3065's reviews (11)Yu Gi Oh! The trading card game that you either love or hate. I am sure that fans of the genre will have already bought this title. If you are new to the game then I would recommend another title in the series such as Spirit Caller. The reason for this is the difficulty of World Championship 2007.This game is pure card dueling. There is no storyline. However, there is still an awful lot to this title. Unlocking new duelists which are set into tiers, level one, level two etc. There is a challenge mode where you have to create specific theme decks. An LP survival mode, Puzzle mode and Limited Deck mode. You can also duel online through wi-fi and down load the latest Leaderboard Ghosts to duel off line. I recommend doing this as it is a great way to obtain higher amounts of DP to spend in the store to acquire more cards. You can also duel and trade cards wirelessly. This I found very useful as by using two DS systems you can trade cards between this version and Spirit Caller.Graphics are clear and the cards recognisable. Touch screen controls are a joy to use. Sound is average. As I have mentioned, the game is designed for advanced/ experienced Yu Gi Oh! players and as such the first few hours of play can be quite frustrating. Perseverence pays off though, and I am totally addicted to this title.Konami, please make the next title in this series have a more generous DP pay out for winning though!
