You will also need to add PlayIntro=0 to the .ini file as well or the intro will crash the game. There’s one for playing at high resolutions as well and an audio dll to fix as well, but both of those are needed on Windows as well.
Edit: even then, the game crashes often in medium/late game. And the load game is a chore because it doesn’t store the last location. Overall it is a pain but I got through university this way playing on Ubuntu.

I love how the Gamebryo site is still up. I thought it was funny it was still up like 10 years ago when I looked last, and it’s still up now without any changes.
There was an option, and some companies did ship a disc with the installation files. Obviously the license was tied to the Steam account and not to the disc, but if companies weren’t shipping the disc with the license, that’s their fault for cheaping out, not Steam.
