signal.noise: Eh, I didn't pre-order the deluxe edition for any of the extras, just to support a polish indie studio that makes great games.
DocRask: Preordering digital copies is of little value. The fear of missing out is artificial. Not like there are limited supplies. Game comes out and it might not be something you that you'll enjoy. Why lock yourself into a cost and time sink gamble? You can still support this AA game company when the game comes out after it's been bug tested by paid streamers and other unpaid adventurous people (maybe fools).
Like I said, I don't do that to gain anything (or to alleviate any fears), so it's irrelevant whether there's any real or perceived value in it for me.
I know I've enjoyed their previous titles, I know I liked what they showed of the game during development, so there's no reason not to just buy it and maybe help the devs a little to gap the time until release.
If I really don't like it in the end.. well, so what. So far I never had a bad experience with pre-orders though.
In any case, I think the price is fine as it is. If you're short on money it's best to wait a year or so anyway and buy during a sale. Unless you fear you're missing out, of course.
