If it wasn't so half-assed it would be fun. There's simply no information about the game that you're involved in. No right/wrong, no score, no nothing. You're essentially just drawing objects in a stripped-down version of ms paint and showing some other random person what you drew. If this is Pictionary simply because you draw things then McDonald's is a 5 star gourmet restaurant simply because it sells food.
The presentation was decent, but without any information showing your position in the game compared to your opponent's, your comparison of this to Pictionary renders this an absolute failure.
