The wiki now has two Linux install guides, one for (traditional Linux PC)
WINE-based installs, and one for
(Steam Deck) Proton-based installs.
To make both guides, I had an AI go through all the existing install guides I could find (here, on the wiki, and elsewhere), and it built a single (well, two) guides containing all their combined knowledge.
Hopefully if you want to install EQ on Linux (including a Steam Deck) the wiki will now have your back!
