If you guys want to gift Vietnam to someone who picked up BC2 anywhere but steam (ea store, EB, FS, etc), it won't work.[QUOTE]You have bought the base game somewhere else, and someone has gifted you Vietnam on Steam - well... Long story. The gifting will succeed. Steam will know that you have Vietnam, but you will not see it in the Steam client because you do not have the base game. Therefore you will not be able to view the 16-digit code for Vietnam. Contact Steam support to resolve this.[/QUOTE]There's probably some assbackwards way of doing it on the EA store and giving your friend the CD key, but I don't know the specifics on that if the purchased key is tied to that particular email account.
