Learn Chinese by playing a game
http://enterzon.com/node/5
Zon is a multiplayer, online learning environment designed to teach Chinese language and culture through gameplay. As a web-based site, Zon provides real-time, on-demand connection to interactive learning activities and authentic cultural information. Zon players are motivated not only by their intrinsic desire to learn more about Chinese language and culture, but also the ability to interact with engaging story-driven plot lines, interesting characters, and fellow players.
When you enter Zon, you start playing at the Tourist level. As you progress through Zon, you can choose to become a Resident – and even a Citizen – of this virtual Chinese world. Before you can progress to Resident and Citizen, however, you must engage in tasks learning about Chinese language, traditions, celebrations and daily life.
