Runescape

Okay I have never played the game my self, nor do I know too much about it. I do know however that this summer, my younger brother became addicted to it. I don't live at home but my parents had told me, that he had become a hermit. He would be on the computer most of the day. He wouldn't go out with his friends, and he stopped inviting friends over. He would hardly eat, unless someone physically brought it to him and he wouldn't go visiting anywhere with my parents. My parents came here visiting mostly every second weekend all summer, my brother came with them like 3 times and when he did, he was on my or my aunts computer and you guessed it he was playing runescape.
