The most hacking I've done to get a Steam game working on openSUSE Tumbleweed is some copypasta sed magic to bypass the Private Division launcher app for Kerbal Space Program 2. Other than that, setting a command line parameter to ensure my eGPU gets used (which should be a relatively uncommon scenario), and forcing a few games to run through Proton, everything just works.
