I don't have anything against Runescape, They've given me hours upon hours of entertainment. Although I do have to say the game isn't as entertaining as it was back in 06-08.
I didn't necessarily leave Runescape for anything else, I sorta just stopped playing. Then my friend suggested to try out RSPS's. Then after a while I ended up at Worldscape.
Any who, It's quite sad how people get that attached to a game that they cry over it and, in extreme cases, even kill them self.
