This was a good and fun experience. Even though this is a tech demo for Source's HDR, This was still was a nice and fun demo. The commentary mode was good as well. Overall, it was nice game to play for half an hour.

Man...Where do I start?
To begin, This game is absolutely legendary and it was extremely fun to play through it again. The gameplay, story, characters, combat, visuals, writing and the level design are all incredible. This is still my favorite Half Life game.

It was a good game. I like how they expanded Black Mesa and the new mechanics that were added. The story was good, the gameplay was fun in places but I wish some of the new features were expanded upon and some of the enemy encounters were not fun.

It was an alright experience, the gameplay is still the same as Half Life 1, the level design is okay-ish. The HD models are not bad but I prefer the original models more and it's not that big of an upgrade. It's really short and I wished there were more levels in it.

A classic and it was a fantastic experience to play. There were some parts that didn't age well to Valve's future games such as Half Life 2 and Portal 2 and there were a couple levels that were tedious and Xen wasn't exactly the best with it's gameplay but in general, this is still a fantastic game and deserves it legendary status.

An absolutely brilliant game. It nails the dystopian environment it's set in and I love the characters and the writing. The gameplay is really fun and great and makes the game special.

An incredible first chapter and it's as good as Chapter 1. The things I loved from the first chapter: The story, characters, combat, humor and music are still here and are still wonderful.

An incredible game and I loved every second of it. I loved the writing, story, characters, combat and the music and it's Toby Fox style of game design and humor is amazing and works really well.

An incredible game and my favorite game in the portal series. I love the story, gameplay, humor, characters and voice acting and the level design and puzzles are wonderful.

A short but a great game. The story was heartwarming and good, the gameplay is simple but I really love the usage of old AOL chatrooms. I loved playing it but I kinda wish it was longer though.

This game is absolutely wonderful and is a fantastic puzzle game. The story is wonderful and the writing is perfect and is incredibly entertaining. GLaDOS is incredible and Ellen McLain's voice acting was perfect. This game stills deserves it's legendary status.

A wonderful, cute and really fun farming game. The environments were amazing, the farming mechanics were great and easy and I love the ending to the story and the story involving one of the characters was great. I loved this game and I can't wait for the sequel!

A beautiful, trippy and psychedelic gaming experience. The story was good, the graphics were amazing and the music was wonderful and the best part of the game. It sucks that the game is short but I had a really fun time playing it!

It was a fun experience but it's not as high as the original. The gameplay was fun, the characters were good and the Arcade mode was fun in places. But the lack of suspense and kind of subpar story doesn't make it as memorable as the original game.
