not well optimized game. basically unplayable.this game is so lag. even in the lowest setting. take note. i have a very good phone and fast internet. so i doubt it's in my end that has the problem. will rate it 1 for now. til they fix this problem. also. when you first start the game. it will download a huge file. and would have to wait a very long time. instead of immediately play the game. and download resources in background. like any other decent game. i love yu gi oh. but this game sucks.
