Action Quake II remains my perfect shooter.
Still has a tiny but active community on discord, also has been re-released as AQtion on Steam.
I wonder if jungle1 and teamjungle are ported? Those were the first maps I made for any game (and I had no idea what I was doing).
I fondly remember a conversation with a random person in a bar, about a decade ago. Somehow, they brought AQ2 into the conversation, pointing to my creations as their favorite maps (without knowing I made them).
That was a good feeling :)
