I would get this and episode 2 on sale, because both are incredibly short and the replay value is limited to achievments.
My opinion on the game itself? Its like an expansion pack for HL2, and I don't really have a problem with that. Its still Half-Life 2, and its still just as fun as that game. They even experiment a bit with the gravity gun in the beginning of the game. There are few new things, but the intention isn't to be a COMPLETE departure from HL2. i like to judge games by what they aim and intent to be, and then see if they go off of those goals. Episodes 1 and 2 are equally as fun as Half-Life 2, with a few new features sprinkled in that I personally found to be quite fun.

Episode One was... booooring even with cheats. You kill and you do puzzles not that fun, Once i buyed this game i was excited i did not watch any lets plays on this game so i dont see any spoilers but i just wasted my money on this. This was plain nothing playing 3 hours straight was misiable going thu nothing but puzzles unlike Half Life 2 this game was bad it felt like i did 3 missions and thats all. If your thinking to buy this watch a lets play on this buying this is nothing. Thank you Gabe for nothing this episode.

If you have not played Half-Life 2, then go look at that right now.

Half-Life 2: Episode One continues right where Half-Life 2 left off. Like, right there, the exact same moment.

So, if you enjoyed Half-Life 2, then no doubt you will enjoy Episode One just as much. The length is considerably shorter, but paired with Half-Life 2: Episode Two, the gameplay compares nicely with the length of Half-Life 2. (Yeah, so you could look at it like Episode One and Episode 2 form Half-Life 3)

Personally I feel that the events of Half-Life 2: Episode One are lackluster in their contribution to the story, and therefore the entry in the series is mostly unnecessary. However, it does provide plentiful gameplay and puzzles, which are what we are all here for anyway.

Already this review is too long. The situation is simple: if you enjoyed Half-Life 2, then Episode One is more of the same, so get it if you feel it is worth playing.

Half-Life 2: Episode One Continues the Story of Gordon Freeman, And Brings some New Ideas into the Table.

GOOD:
Story Writing (It's Pretty Good And It has more Things happening)
Gravity Gun (Again, The ONLY Good Weapon)
Textures
Ragdolls
Voice Acting (It can be Funny Sometimes.)
New Areas to Fight in
A New Enemy, The Zombine!

BAD:
The Worst Weapons in the Entire HL Franchise that are the HL2 Ones still remain.
The Enemy Roster is STILL Hugely Repetitive.
The Music is Again, Boring (The Main Reason why I replaced Every Track with Adrenaline Horror)
The Ally has Died? Save Point return!
It's Short.

Half-Life 2: Episode One is pretty Good in the Story Side, but the Crappy Weapons that I hated In the Last Installment Still remain.

Gameplay wise - it has some great moments; including a standout section in which the player directs Alyx Vance's fire via a flashlight.

Unfortunately Valve became sloppy with this expansion pack - opening with a deus ex machina in the lazyest manner poosible.

The scripted sequences become contrived "look at this" moments with Alyx Vance spelling everything out for the player or repeating "oh my god" or in general, gasping at anything and everything to give a foiced sense of drama.

Basically - it's more Halflife 2, but not as good. It's still a great - great game. Better than 90% of shooters out there, but pales in comparison to the main game.

Would still recommend it.

Half-Life 2: Episode One continues the story of Half-Life 2 with another adventure of Gordon Freeman and Alyx. The story picks up right away after the original game and offers more of the same as the original. There's nothing really new to note here besides some new enemies and a level that puts good use of the flashlight; you also have Alyx by your side the entire time - which allows for some unique gameplay, such as not firing any bullets and only using the gravity gun. Episode One is somewhat short, I was able to complete the game in ~3 hours.

Oh my god! I had never played any of HL2's sequels, but damn, have I missed a lot!
This game is epic!

It's a 3 hour long ride that's so wild and intense that makes all other action games feel dull and flat.
But... what am I talking about? There are no other action games! There's only one king, and Half-Life is his name.

A must play!

After playing this game, and the first one, I felt a great sense of achievement, for Half Life 1 and 2 are brilliant games. Definately recommended those who haven't come to playing it.
