as being discussed in the steam thread, I checked my friend list and apparently 99 percent of it owns SSFIV so..Basically, game is being transfered from GFWL to Steamworks. When this happens, Steam will create a new key for the steamworks version, you'll own a different key.But, the GFWL keys are redeemable on Steam.What does this mean? the Key you own, which you can see by right-clicking the game and clicking "CD Key", can actually be redeemed on Steam right now, as a completely different copy of the game.they will *probably* fix this, and as soon as the switch happens you probably wont see that key anymore, so hey, gift away.
