So people with Humble experience...I was going through my Humble account and noticed there were a bunch of games I never redeemed, probably because they were added after I had stopped paying attention.
There were also some games that I never redeemed likely due to already having them. It is safe to say that if the button still says "click to redeem on Steam", I've never looked at the code, and couldn't have possibly given it away already?
I'd like to give the codes away here, but I don't want to run into a situation where I'm giving away keys to games I'd forgotten I'd already given away.
