Fuk ya man. DOOM will never die. I still open up DOOM 2016 and play that first level on arcade nightmare, just to get a kick.

I've got a folder of all the D1 and D2 standard and freedoom wads. I copy it onto any new linux machine, and I install Boom or whatever.

I have a project that I keep picking up and abandoning for a DOOM OS. Its purpose would be to spin up on a vm, search for a local game, and join a bot to a deathmatch. Each vm would add to the load on the server. How many vms can it run? That's the DOOM quotient. But I'm not very serious about it.
