I used to be addicted to it, my brother played and he got me into it. It was when we still had dial-up internet and we ran up a bill of over £100 in one month. Our parents nearly killed us.
We switched to broadband pretty quicky after that.
I have two accounts, Frogmorton0 and Wulfgar285. I believe Wulfgar is the better one (and is technically my brothers, but when he stopped playing, I started using it). I've not played the game in ages though.
