We know for sure that China is the single biggest country when it comes down to MMO players. According to a recent survey 5 million of WoW players are from China.
If FF14 can tap into the Chinese MMO playerbase I think that would benefit them enourmously.
On a side note, Blizzard has walked over a mine in China. They broke of the deal with The9, which is the company that handles the localized version of WoW in China and now The9 have sued Blizzard in the Chinese courts. According to Chinese media all WoW servers have been shut down for transfer of hardware to another company, but that is going to take a couple of weeks. But that’s only a small part of Blizzards problem. Servers going down for 3-4 weeks, making Blizzard loose many customers over to its rivals, especially the newly released Aion, which at the end of May reached a staggering 3,3 million subscribers only after 2 months of its release in China. Blizzard's other headache is that The9 is keeping its 5 million subscribers hostage until the matter is solved. No one really knows when that will happen. The9 and Blizzard are set to meet in Shanghai Pudong's Supreme Court on June 18th, 2009. If matters are not solved and things drags on there is a chance that Blizzard will pull out from China and consequently loose 5 million of its player base.
