I wonder about this: who pays the refund?  Steam or WB? Its an interesting question, because all steam has to do, is just remove it from your cloud and issue a refund. So my guess as to the costs, are like purchase price + 3 dollars processing. This estimate is on the high side, and its much cheaper then the restocking that would occur at a retailer.  I know the game has been pulled from the steam store. Its damn funny too, as it says "Warner brothers will improve performance" This REEKS of contractual obligation, so every day this is not on sale, WB is losing a shit tone of money, but they may also be paying valve a penalty fee.  this may be the most costly blunder in video game history. More costly then ET.
