Man…I had the same experiences as you with Castlevania games and loved the hell outta Bloodstained. Wish I had more to add but wanted to at least high five lol

EndeavorOS too I would think.

Well Pop is based on Ubuntu, while EndeavourOS is based on Arch. So package availability is a little different. I’ve never really had issues with either but only really checked out Pop for a few weeks. I’m typing this from my EOS rig I play all my games on that’s been stable and happy for maybe a year now.

One distro is fairly similar (or can be made similar) to another more or less if you get into it. I’ve found EndeavourOS pretty damn easy to set up and run for what that’s worth and run it on three different machines right now.
