Funny you should ask, I did, but I honestly don't recall when it is I did that. Might have been when they announced that newsletter promo and I figured the way it might connect back to a steam account purchase would be if I linked them.
I did that because I figured it was needed to make the in-game content show up, which to be honest I've not really checked for because frankly I was going to pre-order this no matter what they were throwing at people to induce them to pre-order.
This thread interested me just because I wanted to change my avatar picture to something Planetfall related.
