Hell yes I want a Steam key. 95% of my 300+ PC games are on Steam and that's where I'd like to keep them. Besides E: D and Star Citizen all of my currently installed games are via Steam. And I don't want to sound rude but, I paid $160 for this game, so excuse me (and I hate to say it) but I think I should be entitled to a Steam key. In fact, why is it even a question of do we want one? Just post them to our E: D accounts and let those that want to redeem their game on Steam do so. It's not going to cost Frontier or Valve a dime; in fact Valve encourages these migrations when existing games debut on Steam.
It's actually somewhat annoying that we have to "ask" FD to do this for us. I find it a little bit rude they didn't think in advance that their existing playerbase/alpha/beta backers would want a complimentary key, as the game WAS NOT available on Steam until now.
I want to see my hours played, I want to upload screenshots and videos to the *correct* hub (as "adding a non-steam game won't post the SS's and vids to the actual hub), I want "official" support of streaming, I want to write a review, I want achievements (if there are to be any). Why should I not get all the features a new steam-purchaser gets @ $59.99, while my version doesn't support these features yet cost $159.99?
If you don't care about Steam features, then fine - don't redeem your key. But don't be a d**k and act like there is no personal advantage to some of us to have the game on Steam.
I voted "Don't care". While I love Steam I won't be putting my copy of Elite onto it as I don't run Steam while playing Elite; I don't want another game downloading updates while I am trying to play.
Um...you know you can disable automatic game updates while in-game, don't ya? (obviously not lol)
