Soft-World, the publisher of World of Warcraft in Taiwan, is developing a microtransaction-supported virtual world. Xenjo Online is notable because it's Soft-World's first cross-platform MMO. On top of the PC version set to come out later this year, Soft-World plans to release an Xbox 360 version in 2009. Few original console games come out of Taiwan. If Soft-World pulls this feat off, they will become Taiwan's largest Xbox 360 developer. Besides announcing the game for Taiwan, there is no information about any plans for an international release.
