Normally we'd be somewhat cynical when talking about an MMO going to a phone. World of Warcraft on an iPhone just seems complicated, while Second Life on a phone just seems unusual. But for MapleStory going to a phone, well, we just can't see much wrong with that. It just seems to make sense, with the 2-D side scrolling action being perfectly at home on a mobile device.
However, don't jump for joy just yet, it's only a version of that's making it to the MapleStoryAT&T media mall. MapleStory: Warrior is the same MapleStory gameplay, just condensed down for your phone. It's sadly not online, but it does connect to your MapleStory account to give you a brand new in-game item. So if you ever need that MapleStory fix and you're just not anywhere near a PC or internet connection, now you have options. Downside, those options are all warrior-based options.
