I used to, then I stopped, for reasons that are unknown to me.
Later I picked up MapleStory and dropped it almost immediately. God, that is the single worst agglomeration of hand-drawn graphics ever to be classified as a "game", i.e. something to be enjoyed and played for fun. At least in RuneScape there was always something to do. In MapleStory, all you do is grind combat skills. Just whacking monsters, over and over again. You don't even train specific stats, you just entertain yourself by repeatedly pressing the attack button, then rebinding it to a different attack and hitting that over and over again, until weeks later you level up, and you receive an imperceptible increase in your button-mashing ability. The worst part is the community, which is so slobberingly mindless that they cannot be even bothered to type properly, nor in full sentences, nor with commonly accepted abbreviations. Upon entering a town, you will find it full of motionless idiots, all with the message "afk fame pl0x" or some bizarre rendition of those letters, frequently with random spaces inserted. And why "pl0x" as an abbreviation for "please"? Why? "plz" is the usual abbreviation, and "pl0x" just makes it one character longer. What finally made me quit, however, was my friends. I had played a Mage, and placed my points in several different skills, essentially whichever one appealed to me at the time. My friends, learning of this, told me I had "screwed up my character", and that I would never achieve my maximum damage output. They advised me to start over, weeks after I began.
Now, I can partially understand a game that feels like work, especially for children my age, who want something to care about and be knowledgeable about. A game that feels like life, however, is something I find hard to comprehend.
