YES! Finally Valve Software has decided that soon all Steam users will be able to sell or give away their own “used” games off their Steam accounts. Here is what Gabe Newell said:
“We are happy to announce that soon (May 1st) all Steam users who bought at least one game using Steam will be able to give away or resell their own Steam games to their friends. All of the funds gathered from their sales will either directly show on their credit card balance or Steam Wallet, so right now you don’t have to worry about buying a shitty game as you can simply sell it to someone else.” – Gabe Newell said.
Additionally Newell mentioned the new, improved refund policy:
“We really like how Google Play (former Android Market) handles refunds so we’re about to introduce a similar refund policy. You’ll have 12 hours to return any game whether you played it, liked it or hated it. Simple as that.”
Here are some leaked screenshots of the upcoming feature:
