Hmm, I'm gonna throw a little blasphemy in here. Back in the day HL1 was mind-blowingly amazing FPS that changed everything. HL2 was even better. But playing HL1 again now 14 years later...this is kind of a long, dull game. The combat has never been a strong point of the series, and it feels even more dated now. There's little enemy variety, lots of similar sections since it's a lengthy game (how many vents do you crawl through) and the puzzle platforming controls can be kind of janky. It also lacks the narrative push that Half-life 2 has where even if the gameplay wasn't doing a lot of things the story would be advancing and keep it interesting. HL1 is kind of a lonely solitary experience. It's definitely a classic, but I don't think I'm going to finish Black Mesa when I just feel like I'm going through motions and would rather be playing a more interesting FPS. They did a great job with the remake though!
