Just a quick question as the Bethesda Bundle keys finally arrived. You can still sell a key even if you revealed it on GamersGate as long as you never actually redeemed it on Steam, right? I know there's a gifting option, but wasn't sure if that would be needed to transfer a key.
Yes, the keys are entirely separate from GamersGate and are handled by Steam only.
So as long as you didn't redeem it, you can sell it.
