auxiliary information: The Yu-Gi-Oh! Trading Card Game, known as the Yu-Gi-Oh! Official Card Game in Japan, is a Japanese collectible card game developed and published by Konami. It is based on the fictional game of Duel Monsters created by manga artist Kazuki Takahashi, which is the main plot device during the majority of his popular manga franchise, Yu-Gi-Oh!, and its various anime adaptations and spinoff series. The game was launched by Konami in 1999. It was named the top selling trading card game in the world by Guinness World Records on July 7, 2009, having sold over 22 billion cards worldwide. As of March 31, 2011, Konami Digital Entertainment Co., Ltd. Japan has sold over 25 billion cards globally since 1999. The game continues to gain popularity as it is played around the world, mostly in Japan, North America, Europe and Australia, and has been expanded with new rules and additions as the franchise grows. From March 2002 to December 2008, Konami's trading cards were distributed in territories outside of Asia by The Upper Deck Company. In December 2008, Konami filed a lawsuit against Upper Deck alleging that it had distributed unauthentic Yu-Gi-Oh! TCG cards made without Konami's authorization.
