Duelists be warned, if you play this game you will be addicted to it!!! No seriously. I bought the game three weeks ago, and I am still addicted to it! This game has many features such as download-able cards, and download-able restriction rules. Yes you can update the rules! This game has cards up to Tactical Evolution + more. Cards like "White Night Dragon," that have never even appeared in a pack is quite common in this game. The game is a little hard compared to the starter's deck the player starts off with, and the fact that he opponents actually has good strategic play. However, once you get a hold of some packs the game gets somewhat easier. If you are not a fan of dueling I would recommend that you do not buy this game. This game also has some fun mini games such as "Survival Dodge ball," reminds me of those good old Gun Bound days. This game is a must buy for hardcore dueling fans!!
