I only played EQ for the first year and got out about a month or so after the first upgrade. I had a lvl 50 magician with the full "hate" gear and then I took him to lvl 57 (with a lvl 40+.. hell.. what was that class that cast SOW?). I sold the account on ebay for $1000. IT was on the biggest server at the time.
I moved to DAOC and played for a lil over a year and sold that account for $1000.
Then I went back to Ultima Online for a year and sold my accounts for another $1000.
