no it would leave things up for scaming
that's already a problem oin steam
sorry we don't want oto make it easier for you to make your games profitable or phishers find easier ways to earn money
if you want to trade games buy it from your friendly neighborhood etailer and email the coide and you take the risks
fyi that wouldn';t work anyways as it would be region restricted
sorry the point of ms points is not TRADING
FYI it is against the terms of use and a clear violation to do trading
also DLC is region restricted you cannot "trade" or GIFT something from a US region to a UK regional account
its your own incoime to buy games not trading
