I know several people who still play the game. Still plays like shit due to low FPS, netcode and completely nonexistent weapon balance. But it's fun, damn it. Black Mesa multiplayer used to play better but they've turned it into shit with one of the later updates. What sort of idiot removes the server browser...

I believe it's due to the fact their school system gives them some notebook that has pretty basic specs, like 4GB RAM.

So that enables them to play older games but not current ones.
