I thought I wasn't going to be able to play Age of Empires on Ubuntu. Turns out that I was wrong and, as I am writing this, I am playing it over there. First, a quick AI-assisted search did the trick. But then I am going go over some specifics that helped me: 1. Launched Steam from the Terminal, otherwise I think one doesn't know if it's loading - simply use the `steam` command. 2. Verify that Steam > Settings > Compatibility is working/active - I am using (or at) Proton Experimental. 3. Many times I tried to launch Age of Empires but would get stuck at the intro thinking it won't work. To fix this go to AOE II on your Library > the cog icon > Properties (enter the game's properties) > Launch Options > use `SKIPINTRO`. Nice. Btw, am running Ubuntu 24.04 LTS.
