Yea, I see Runescape accounts and WoW accounts all the time for sale, mainly on craigslist and some are really amazing and worth alot as in over $2000, I have a friend in school who's account(s) are worth over like $3250 on WoW because of all the stuff he has and how many lvl 80's there are. Its amazing that playing games can make you money once you get sick of it, but its not a full time job by any means, hes got alot of time into it.
