It's a shame this is only accessible to backers, I'd love to play it anyway
A lot of people will get this as it's for those who backed at $100 and above. Many of those people are PS4 players who do not have gaming PC's. I'm not sure on the logistics on whether it will be a EGS code or not, but if that's the case you can expect a lot of unused codes in the wild. If it can be used by anyone expect a lot of backers gifting theirs away or them being sold on ebay at high prices I guess lol.
