Obviously not applicable to OP since they want to pirate but I'll add my two cents and say that BTRFS would cause Steam to freeze my computer. Disabling CoW on impacted directories made the problem lesser. I have since switched to ZFS and couldn't have been happier with it.
I tried it like a year ago maybe and it was a very interesting concept, but I couldn't find what it really brings to the table over Guix or Nix. I've used Guix quite a lot since then and found that the separation of packages was afaict very similar, with the added bonus of having a completely reproducible system. Maybe Gobo brings something that Guix/Nix does not, but in my time of testing it I couldn't find anything.
