Theory on Permanent CS Equips

Maplestory cannot be a 2d game forever

Why not?

Let me introduce you to a game company that makes $1m dollares every day: Zygna
They've been heralded as the most profitable company ever.

You know what they're most popular/profitable game is?
Farmville

You know what they released as a sequel?
CityVille

You know how they make their money?
By selling in-game currency for real-world cash.

Nexon doesn't have to move from 2D to make more money. In fact, it's that accessability that makes the game so damn popular.
Maplestory is not a game that sells on mechanics; its profitability lies in its social aspect.
Full 3D not only means a more complicated game, but it means that those with older rigs will be left out.

Tangents aside, yeah, you're making a far-thrown conclusion.
If your theory had any grounding, then they would have never changed the permanent option to be a timed exclusive for new items.
They lost money by making everything permanent, and their realization of that prompted the change.

The only reason they even have the permanent items is because they realize that there are some people who simply would never buy NX for items that expire.
By adding the option, even for a limited time, they increase their customer pool. Believe it or not, these changes aren't willy-nilly. They have analysts who try to figure out the most profitable was to distribute their pricing plans.

Plus, I'm pretty sure that the current policy is that every group of new cash items have the permanent option available until the next group is released. That in itself would indicate that permanent items aren't suddenly returning as you insinuated.

PS: @Eosian, I was gonna just comment on a couple of your posts, but I decided that I should just ask for you hand in matrimony instead.

You're correct, English is not my first language. Let me ask you something, do you give blinds and cripples a hard time if they have trouble seeing and walking?

If I warned a blind person that he/she were about to walk into a wall, but, he/she got all peachy and whiny instead of being thankful and acknowledging that they were heading the wrong direction, then, yes, I sure as hell would give them a hard time.

Not being a native speaker is no excuse for being a douche.
