in many Asian countries, the majority of the kids who play MMO do play them at internet coffee, there are literally 1-2 of those internet shops at every street corner everywhere.

The thing is that most of the shops have rather cheap and not up to date hardware and while games like WoW, Ro and a zillion of other asian free to play and PtP MMO games run on every machine, FFXIV does not.
Nor was there any prepaid card based payment method introduced for FF yet.
The games are not played by monthly subscription, plus all installed games must function with any account, ergo no unique IP, serials and so on.
