Honestly if anything RS has made my life better. It has let me learn about the world ahead because of my friends on it, it has made me better socially IRL so I have much more friends than before I played it, it has also reduced my aggressiveness towards friends and honestly it makes my family better because I leave my brother alone when we're forced at home together as before I would always shit on him. My mother doesn't mind that I play it, I could care less about my father because he's the one that divorced her when I was 3, and it is also the reason why I have NO stress because it unwinds me. And now that I'm 14 and I don't play it as much as I used to as I don't have as much time on my hands it has made my character much better around people.
If anything the only thing it has damaged is my skin color as I'm not as tan as most of the other kids at school. But I'm not bullied because of it or anything as pretty much no one hates me at my school as I'm not a faggot to anyone (because of Runescape) and because I'm friends with most of the kids above me on the "social ladder." So all in all, I thank Runescape :s
