Searched around in the FAQ but no clear answer to that question.
I have a non-steam Imperial Edition of the game. If I get the Morrowind Upgrade on steam can I use that on my account and in the process convert/link my exiting account to my steam account?!
@ZOS_GinaBruno
Only reason why I want to do that, is that I own an NVIDIA Shield and currently launching the game on my TV with gamestream requires me to input my login/password, which I think you can skip on the steam edition since it uses steam authentication if I'm not mistaken.
