I'm retired from RuneScape also. The loss of my blue mask really put my hopes down. I choose not to play because I lose to much time from doing other things I want to do. I feel like a better man now, spending more time with my family, getting my homework done a lot quicker, and occasionally playing Quake 4 online or other various things.
I do agree that they are increasinley*(spelt wrong?) changing to many things that it was driving me crazy, trying to keep up with all the new updates, which made me play more hours.
I can't make that decision for you, but all I'm saying is play it if you must and if you have free time on your hands. I could remember when I was really addicted to it and when I think back to it, it's just awful. All those hours I could have used for something else more worthwhile. I hope this provides you with some advice, and isn't just a bunch of garbage.
Oh, counter-strike rocks!

=P. Do you play in any LAN tournaments? I've played a few for Quake 4. Only won one tourny =).
