Nov. UPDATE INFO

Every move back is 25K NX used up no matter how it's paid for. Nexon is smart to encourage people to do this from a financial perspective, but it leaves all the sad losers stuck in low population servers.

It also leaves Nexon having to maintain an empty server that will earn them no money after the first three weeks are up. And with players (the "sad losers" you mention) who tell their friends that "MapleStory is boring, there's never anybody on" because they don't know other servers are different.

But I guess Nexon can do their $$ math better than us.
