Interestingly, Gamasutra notes that the only outlier in the data is Tencent, operator of a number of traditional MMOs as well as the wildly popular League of Legends. That studio has managed to grow significantly. Niko Partners notes that this growth is a direct result of non-traditional titles like the MOBA it publishes in China. As Niko rep Lisa Cosmas Hanson noted, "For several years Niko has cautioned that the repetitive theme of cultural mythical history MMORPGs in China was beginning to bore gamers, and that new types of games would be necessary to revive waning demand for those games."
If you consider the size and importance of the Chinese online gaming market in the grand scheme of the industry, this paradigm shift could be a look toward the future of the MMO genre.
