Half Life 2 was not only mind-blowing, but also my introduction to a relatively newfangled thing called Steam that I was NOT a fan of at first (DRM-wise). Through the years I acquired 2800+ games on the platform, as a sort of digital hoarder with the hope of at least trying every game I purchased (often in bundles/sales) as an exclusive PC player - before I got too old or too dead. I just don't see that happening anymore... Just not enough time left but to sample.
Back to HL2 - it's the 2nd game I've ever finished twice (FF VII being the other), still love the story, the very cool physics gun, the incredible dystopian narrative and setting, and it holds up today wonderfully 19 years later.
It's a shame we'll likely never see an HL3. There are so many talented development firms they could outsource it to, with current engines like UE5, it would be fantastic with the proper writers. Maybe even the original ones. Alright, done gushing here.
