Maplestory

A free and legal drug that's more addicting than crack. Once you're hooked, you'll want more and more, and you will become sleep deprived with no social life. Some even go so far as to steal their parents' credit cards to buy pixelated clothes and accessories. Don't let the innocent and cute looking mushroom fool you. The first time you see it, you will laugh, but once you're in to it, it will be serious business.
