Probably anyone running Linux is aware but I thought I would mention using the new Steam Proton tool with Steamplay, I have tried ES2 and Endless Legend. Both are working without any noticable issue for me. I did a search for "linux" on the forum and it seems it was a highly voted request three years ago, then the project was put on hold. No worries now! You will need to set a launch option in steam for Endless Legend. -useembedded

I posted this in the ES2 general forum too but thought there might be people with just one game or the other interested in this. I hope that's alright.

Great to hear, thanks!
