Got linked to a SCP-3008 game and followed the links to discover the creator had 2 other games as well. All of them are listed here: https://nmkd.itch.io/
Followed some links and found the guy's reddit account (which is very active). Sent the following message:
Ahoy hoy! I'm from the licensing team on the SCP Wiki. I noticed you have several games available with SCP Content. Specifically the three games listed here: https://nmkd.itch.io/
First of all, looks like fun. But I also noticed the pages don't include proper licensing information for the works. All SCP related content is under a Creative Commons 3.0 Attribution/Share-Alike license.
This means that derivative works (like games) must be under the same license with the same terms. It also means you need to credit the original author of the works (SCP-3008 for instance has an author named "Mortos"). You also need to link back to the originating articles (the SCP-3008 page would work for that game, as an example) as part of this attribution.
None of this affects you elsewise. Just let me know when you've brought your products into compliance and I'll give them a look to make sure everything's up to snuff and put this to bed.
Thanks for your time!
Will post again when I get a response. If I don't get a solution then I'll follow up on solutions.
