The Big Bang ''Hot Time'' Event

There is no way Nexon has 6 million people playing GMS. The real figure is closer to the 300k facebook "likes" on their homepage. Sure there might be 6 million characters that have been created but that does not equal the number of players. Nexon love to scam the media.

If you look at the bottom of the Nexon forums you will see:
"There are 9,237 guest(s) online. There are 358 of 408,472 member(s) online"
Look at the other forums, eg Mabinobi or Combat Arms, and you will see the same number, 408k.
So that would appear to be the number of accountsd that Nexon has.
Assuming that some of those 408K are playing other games and not MS, and that many MS players have multiple accounts, and many of those accounts would be abandoned, there might be only 100k or so actual MS players, maybe even less.
