Inn System? what is this?

It can be adjusted, such as 3-4 weeks for a Maple equivalent system, or even 6-8 weeks.

The point is, Nexon doesn't gain anything from forcing players not to play. Blizzard already has your monthly payment, they don't give a pomegranate whether or not you're actually in game. For Nexon, players not in game means that those players aren't being influenced by megaphones or their peers or sales or whatever, and thus are less likely to buy NX. In fact, there's the distinct possibility that in that 3-4 week period, they may find something else to do and never come back. That's really bad for them.
