I used to play the game all the time years ago (2006-2010). I checked the game out again after a couple of years, and I hated it. Maybe I was just annoyed that so much had changed, but the game just didn't seem fun anymore. Jagex changed the combat system after 11 years (who does that?), and many of the things I would do for fun were just, gone.
The game is a shell of its former self, and I would not recommend it to anyone, young or old.
