I remember back in the day I thought one of my favorite games, Elite: Dangerous, would never run on Linux. I dualbooted for a while just so I could play it. After a while I stopped playing it much and figured I could get rid of Windows, so I did. About a year later the community came out with a complicated setup you could perform to get it running on Linux through wine. It's just as you said, lots of manually finding and installing libraries, tweaking environments, and eventually got it working (jankily) at a pretty mediocre framerate. I thought that was the best I was going to get. Another two years and it was running seamlessly on proton with no configuration or tweaking at all. It really is incredible what Valve has done for Linux gaming.
