I was exploring and came across Pocket Planes, which had its servers shut down in 2015. Turns out they relaunched last year, so I’m going to give it a try again.

I used to play Doom way back when it came out. I recently started re-playing it but in Linux using Zdoom, plus the Brutal Doom mod, and it still is one of the greatest things that happened to PC gaming.
