Natsume Game Master was a contest printed on the back of the Pocky and Rocky instruction booklet. This contest was opened to the resisdent of Canada and the United States and consisted at beating Pocky and Rocky and taking a picture of yourself in front of the final credit screen.
The first 100 players to send their picture at Natsume were to be immortalize at the headquarter in addition to receiving a certificate proving that you had overcome the challenge and a sweatshirt. Other rewards may have been planned but unfortunatly none of them came to fruitition.
Now, the Natsume Game Master title has faded from the memories.
