And it wouldn't be feasible in SP, because SP games don't require the number of hours MMO games do. The MMO stuff is all about the grind, the tireless waste of time in order to find better stuff. In SP, that has to be a lot shorter to keep people interested, as grinding shit gets *really fucking boring* unless you've got the social aspect to keep you going. So if you have an SP game with an online auction house, I don't know it would really work. You'd either have to make the items really super rare so that players *have* to get them via the AH most of the time, or you'd just have an AH flooded with items that anybody could just get in their own game.
