How-to question - giving away games already in my steam account

No.

ayy lmao

The only thing you can do about them is asking the Steam Support to remove them from your account and providing a good excuse, otherwise you are damned to have them forever in your account. (Free games can be removed easily tought)

As Jasmine said, "No." You can't give away a game that's been activated on your account. You can give away a game that's in your inventory, but not something that's been activated.

dang, I really want to get rid of Streets of Moscow. seriously, i think it's worse than bad ratz...
