I noticed recently this post: https://www.steamgifts.com/discussion/Dtclb/warning-some-humble-bundle-keys-now-unrevealable-after-three-years
And decided to go through my unrevealed keys on Humble Bundle and give away the ones for games that I already own or don't want.

As there is always a chance that a key might not work (especially for old bundles), I kindly ask for your permission to remove this giveaway if that happens. It would be much appreciated.
