I'll be honest, that number is much higher than I expected.
Community for memes about the goldsrc/source engine and Valve games.
I installed tf2 last weekend after a 5+ year break because cs2 axed arms race which was basically the only mode I used for quick play. And deathmatch is shit, enemy pops up from nowhere, it's dumb.
There's a custom map out there for hl2dm that's a take on soccer, but the ball is really heavy and can kill you as it's jettisoned by your opponents gravity gun. Hella fun.
Throwing toilets at people with the grav. wep. was something special and unique
I still play HL1 servers. It's so much better, but equally dead at certain hours
I loved that game. Ran a server for like 3 years.
