In china you can buy a wow product on a USb. I havent used it, actually they sell it in the 7eleven's here. I'm not usre what it is, the whole game for transport or so you can play in computer / internet cafes and not leave data on the computers eg logins etc. Next time I see one I'll ask a few more questions and take some photos. From memory it was 180RMB ish about $25US.
