Can I transfer a game over Steam?
I have three games, on Steam. Shadow of Mordor, Risen 3 and Lords of the Fallen. I have downloaded and played Risen 3 and Lords of the Fallen. I have only downloaded Shadow of Mordor.
Can I sell them to my friends so they can play them on their computer? I am unsure if they can, considering I have downloaded them on to my computer, already. Is it possible to transfer the files onto their computer so they can play them?
Solution 1:
No, this is not something that you can really do. If you had bought the physical boxed copy, you might be able to sell that (although sometimes having CD-keys registered to an account makes ownership of the physical disks meaningless).
You are not generally able to transfer ownership of games purchased through digital distribution services like steam. Once you have effectively "claimed" the game by downloading it, the game is no longer transferable.
One thing you can do with Steam is register your friends as 'family', and then use Steam Family Sharing to share your games with them. There are some caveats, however. Your friends would only be able to play games from your library when your library is otherwise not in use. If you are playing a game, they can not play any games from your library.
Solution 2:
You cannot transfer the games, but under some conditions you can ask for a refund.
Then what you do with the refunded money is up to you.
