I went to pre-order Summerset via Steam and it gave me a warning message that I was purchasing a game I already owned (Morrowind, which I bought via pre-order when it came out). I backed out before completing the purchase just to be on the safe side.
Is there a special version those of us who already own Morrowind are supposed to be selecting? I don't want to pay twice for what I've already got, I just want the Summerset expansion.
Thanks
