Completely accurate, the mechanics of the game shown on this animation are top notch, I've never seen such dedication to something that most consider 'not needed'.
Yugi and Kaiba's characters are well represented here, completely accurate to the show and manga.
The jokes are totally awful though, I did not even laugh once.
The animation is horrible, quite disgusting to the eye.
Over all, I give it a 5/5 from the perfect application of the lore.
