I own GSB and all of the DLC on Steam, but recently got the DRM free version of the base game from the latest Humble Bundle. Is there a way to transfer the DLC from steam to my DRM free version of the game? I prefer DRM free to anything else, and would like to play this on my other desktop and laptops without installing Steam. I love GSB, but not quite enough to rebuy all of the DLC again. And even if I talked myself into it, I’m sure my wife would string me up for buying it twice.
