I mostly backed everything up to LOVGC. There are currently 580 press kit entries created which you can browse at:
https://lovgc.com/games/presskit
The main ones we talked about but I haven't gotten to yet are Death Stranding, Cyberpunk and Division (games with entirely too many kits). Everything else and then some (minus the trinket kits) should be uploaded. I have about 100 more to go. Some are trinkets and I might not upload, some (30 or so) I need better photos of (like Agony Press Kit).
Let me know if you see anything missing. As a reminder LOVGC allows you to mark the items you own, as well as create wishlists.
For now it is only photos and the title. I am looking for a moderator to help fill in the actual information. If anyone would be interested please reach out to me and I can give you access to start chipping away.
