It isn't possible to trade games you have already activated on your steam account - you either need to have a gift copy in your steam inventory or have a key that others can use to redeem the game on their account
Oh thanks man I'm new to this. I was actually curious as to how this worked because it would be easily a usable the way I thought it worked lol. Oh well...

Make your best offers :D
I tried to manually filter out as many of the free games as possible, but may have missed a few. Ignore that.
Also note that some of these games have a certain sentimental value to them and I enjoy some more than others. Those ones may take larger offers (Example would be Garry's Mod I play that game constantly with my pals :D)
