its very simple if you like yugioh this is fantastic best ever 100% if not stay away as you will find it boring.
The touch screen makes the game a lot more comfartable to play you dont have to constantly press the directional button and stuff.
The games offers a good variety of cards and it will last for ages if you are in to the game a bit like pokemon was.
The score i give is based on someone who likes yugioh so dont jump to conclusions.
One major problem with the game is that the monster details are not as great as they could be ifthey were better then a lot more people would buy it.
The next game should take on more of a pokemon rpg perspective then go form there.
