Dragon Oath, also known as Tian Long Ba Bu in China, is a free-to-play massively multiplayer online role-playing game developed and published by Changyou.com and Sohu and launched in May 2007.

Since its initial launch in China, ChangYou.com has taken steps to sell Dragon Oath on an international stage.

[citation needed] Dragon Oath is set in a world based heavily on Buddhist cosmology and the concept of the Eight Races of non-human entities.

Each has his own unique and important role to play, and is instrumental in shaping the game world players find themselves in when they spawn into the Kingdom of Dali for the very first time.

[citation needed] As part of its continuous efforts to spread its flagship brand worldwide, ChangYou.com announced in 2011 that it will release a new, fully localised version of Dragon Oath, designed specifically for the Turkish market.
