Is Global MapleStory dying?

Dying? Lol. Nexon is still earning massive amounts of income and more people every day are registering and playing the game. It's only the minority(forums) that think that these "hackings" are a real problem, when you only have to ignore such insignificant stuff.

MapleStory still has a good 2-3 years left.

I'd consider that kind of time frame "dying."

I agree. It doesn't have to die in the next few months to be considered 'dying'.
That said, though, the hacks will get worse unless radical changes come in. And, seeing Nexon as it is, that's not gonna happen.

Nobody here cares about Nexon's revenue and neither do you. The game doesn't have to be shut down to be declared a mountain of feces.

Uh huh.
