Console games don't sell across many parts of Asia. Too much piracy. But online games that milk you for microtransactions, they work much better, explaining why the series is going online for a new Asia-only title.
It's been announced that the popular basketball series is heading to China "and other key markets" in the region, in the form of NBA 2K Online.
The game will see a PC version of 2K go online, and...that's about all we know, as 2K's announcement was 100% about the NBA's popularity in the region and 0% on how the game will actually work.
If they were to announce something along the lines of "you pay to unlock better players and new uniforms", however, we wouldn't be surprised.
