Ok i was on Wikipedia and forsome reason looked at nexon corporation so it says this...
Partnership with Nintendo
NEXON announced that they have made a partnership with Nintendo,[2] though they will continue games for the computer as well. Together, they are currently working on MapleStory DS for Nintendo's handheld console, Nintendo DS.
No wait I saw something like this a maplestory on a portable consolo like a year ago o.O but it was korean or so...
No wait, I think they changed it to English, and players can play with each other in groups of like 12 or something. Other than that it's very different.
Off-topic ish : How does Maplestory have anything to do with Combat Arms, besides being owned by the same crap company?
