I've played almost all yugioh games but this was the first yugioh gx one i played it has a different style and ROCKS!
This game also offers alot of new content such as the cards and this time when you enter the password to a card you like you actually have to pay which gives this game more challenge. This game also gives events such as after class whether you wanna walk with a specific student or not and eventually you trigger events after walking with them. Yugioh Gx also offers other challenges like the tests you take to keep your rank or move down and also lets you battle duelist whenever you want by either scheduling a battle during a weekday or finding them during the weekends. This game also offers a ton of other duelist to challenge to keep things fresh.
The bad part about this game though is the duelist talk during duels so u have to press a to skip it but i like reading what they have to say. But Overall this game is an amazing game even if you are not a fan of yugioh
