What are y'all using for your offline game libraries? I ended up getting Resident Evil on GoG and started thinking about how I can host these on a NAS. Maybe something Dockerized?
I've been keeping an eye on GameVault as it does exactly what I want from a server perspective. I'm just waiting for a Linux native client or integration the HeroicLauncher or Lutris. The devs are pretty active in this community too!
Like they say in their FAQ it's source available but not open source
No, GameVault is source-available, meaning the code is open for you to explore and modify for personal use. However, you may not use it for commercial purposes.
They also have a paid premium version which is required to use third-party clients, so there will be no heroic integration unless you pay
