I did a quick quick lookup of Stern games on IPDB.

Using a three year sample, 2017-2019, they released roughly 11 original titles in multiple price tiers.
Aerosmith
Star Wars
GOTG
Iron Maiden
Deadpool
The Beatles
Munsters
Black Knight
Jurassic Park
Elvira
Stranger Things
In my personal story, I purchased 2 of these NIB and two of them used. I’ve already sold the two used ones as I didn’t have to take much of a loss on them. Since the new games will have a higher depreciation, I’ll keep them longer and get some that value out of personal enjoyment. Price is certainly a factor, but the PF issues are a much larger consideration for me personally. All of my four purchases were before 2019.
I am very hesitant to purchase new until Stern addresses the issue. I completely understand that they are not going to make a public statement about the PFs. However, the problem is real to collectors. It’s hard to know when a problem has been addressed if a company won’t admit it exists.
