Once I've bought a physical copy of a game and activated it on Steam, is there any way I can return/recycle/whatever it? I realise that should I want to re-install the game later the dvd would make it much easier/faster, but I don't think that potential gain balances the pain of having to carry around 20-30 game boxes every time I move (about once a year).
I don't expect there's a lot I can do, as I don't want to give away the games (i.e., I want to keep it on Steam), but just throwing them away seems wasteful, and I don't think anybody would actually pay for a dvd, even dirt cheap, just to make their own installation faster (if that would even work).
Any bright ideas? Anything I can do?
