Lineage, RO, and other Korean MMOs shouldn't really be placed in the chart. The Korean billing system usually consists of charging the Net Cafes usage of the game, and let the users play free. You can buy home versions and pay a monthly fee and all, but it gets really hard to check numbers.
Uh no. Even on Net Cafes, if you want to play you gotta have an account, meaning you gotta pay a monthly fee. The Net Cafes only provide you a computer with a game installed, not an account or characters.
