How many Black Knights (Black Wings Generals) are there really?

A)Game runs out of plot material
Wow, is that even possible? Simply point one continent named Masteria and you'll know how potential or plentiful are those plots in it

You read my mind. I even had the chance to see Krakia's deeper layers today - and boy was it awe-inspiring!

B)Players all quit
nah, impossible,unless Nexon made a requirement of NX to continue playing
Given how Mabinogi's about to suffer the kRO hacker attack towards its own database, Nexon just might need to to keep assholes like those dupers out.

C)Company stops making extra content
Will they if MapleStory kept bringing in them endless profits?

There's numerous amounts of resources for them to use, storywise. It wouldn't be that hard to create new areas - hell, make a user-created area event. Just keep the Narutards and Bleachfegs out of it.

But then, Nexon has too much forked up storylines from one and another
they'll eventually forget to fill in the blanks then
"HOLY SHYT ! FAREWELL MAPLESTORY ! HELLO MAPLESTORY 2 !"
I said this specifically to those who keep blabbering about the Black Mage being the "End of MapleStory".
