Quoted from The_Casual:
Well, it's an interesting business challenge from Spooky's perspective. Do they ostracize the current Fang Club members who were supporting the company before this announcement or do they disappoint their new 1,000+ prospective customers?
If they keep this membership as a "paywall" of sorts, the 750 games will only be sold to the Fang Club members. Many of which joined solely to access the pre-sale.
It's tough, but it's a decision that Spooky is going to have to make.
You are overthinking it. You have to be a member buy January 7th, 2020 because the goodies will ship out January 8th, 2020.
It probably has to do with when you signed up for the Fang Club. I'm # AB-1066, so I'm guessing I was the 66th order to be processed. Which seems crazy, because I was in as soon as I saw the posting...before the Rick & Morty announcement.
