I have a couple of uplay games from Humble Bundles that I will never use. Can they be used by anyone if I give them the code ?
Hope this helps 5.5. No selling of Humble Bundle codes. Resale of codes obtained through Humble Bundle is against its T&Cs. Gifting / donation of these codes is permitted provided it is using their gift option.
Those are our forum rules on the subject. However if you mean "Can I sell them via Kinguin or Ebay or something?" then the answer is yes but on the Ebay standpoint be prepared for someone to accuse you of a dodgy code and get their money back and you lose the code. Unless the games are worth loads of dosh you might be better giving them away to friends or offering a swap for something you do want.
