MapleStory-Little kiddie's coming from runescape with small anime characters and huge heads. Jump around, kill monsters, there's a cash shop which is basically the foundation of money making, little kids taking credit cards. You get the idea.

Maple Story is honestly one of the most addicting games in existence. It's almost close to ever-crack.
