I didn’t say it was HL3. I replied to a post implying the series hasn’t had an update in 20 years.

It’d be like a Star Wars fan wondering why there’s buzz about the movie coming out next year despite it being 42 years since Return of the Jedi. And the answer is that even if that’s the last one that particular fan personally cared about, there has been Star Wars media since then.

Also, Alyx did resolve the HL2E2 ending. It didn’t add a whole lot on past that, but the cliffhanger was very much addressed.
