I was in the beta for the original World of Warcraft and restarted when it officially launched. This was 20 years ago, so memory is fuzzy, but somewhere along the way I was playing it in wine exclusively under Linux. Game updates were common and frequently broke wine, but I kid you not a patch was available within 24h. Yes, this forced me to compile my own wine, but it wasn't that difficult then. Together with "checkinstall" I could maintain a clean .deb package from the source code.

Some links I found in a quick search showing the challenges:

• https://www.linuxquestions.org/questions/linux-games-33/world-of-warcraft-in-wine-success-485886/
• https://forums.gentoo.org/viewtopic-t-311551-start-0.html

To be honest, keeping the game running in Linux sometimes felt as a fun side quest!

After that I was mostly able to play all my games in Linux, with some exceptions, obviously, that sometimes required me to install windows.
