// I post this simply because it's a significant event for the game industry in China...

The 2009 Game Developers Conference in China is enjoying the support of two key groups. Event organizer Think Services Game Group (also owners of Gamasutra) announced that two Chinese government agencies within the country's Ministries of Industry/IT and Culture fully endorsed GDC China 2009, taking place in Shanghai from October 11th-13th.

//Again, the so-called cultural gap took place in the market?
//I just wanna point out that Monster Hunter is not Pokemon, at all!!!

Enterbrain, publisher of weekly Japanese gaming magazine Famitsu, revealed the 100 best-selling video game software in the region in 2008.

Capcom's PSP action role-playing game Monster Hunter Portable 2nd G, coming to the States as Monster Hunter Freedom Unite this spring, was the top-selling title for the year, with over 2,452,111 units sold since its release in March 2008.
