My girlfriend's brother plays Runescape all the time. He paid to become a member so he could get all the "rune" armor and gear.
I've always wanted to try dawn of war, but just never did it.
I am a recovering WoW addict. It was pretty serious. I wanted to be the best player, with the best gear, and it consumed me. My friend and I were clocking over 100 hours of playtime a week (using xfire)! Not to mention I had college, a part-time job, and girlfriend. I quit before the expansion pack came out. My friend still plays, and I watched him for a while. The expansion would require me to play less and gain more from it... but I still don't want to tempt myself.
Let's hear from all you other gamers out there, keep this thread going!
