Wow, you’re right. I could have sworn it included Source SDK at some point, but it’s certainly not showing up now.
I can’t think of any reason at all to get HL: S at that rate, unless it allows for carrying Health, Suit Power, and Ammo the way that HL2 does. Even then it falls short of really justifying the purchase.
Play the original. Stay pure. Also get access to the tons more mods available with it.
I use to be a half-life source, but then I played the original half-life 1 and I liked it alot more.
Didn’t know that the Source version was lacking the AI conversations.
Anyway: Due to the Source engine ladder bug and the weird map texture errors valve left in half-life source, get the original, not source.
Play the original, not the Source version. The Source version just feels sloppy in so many ways. And gibbing is all but gone 
Oh wow, I just started HL Source and went straight into the chapter “Apprehension”. One of the HECU walked straight through a closed door, an MP-5 was just floating in the air, and the ichthyosaur and the scientist who falls into the water were both stuck there completely stationary in the water! HL:S ftml
I only got to the first gargantua, and now I don’t have half life 1 anymore. What should I do??
That’s like a third of the way through, absolutely get it and finish it! Unless of course you weren’t bothered about it, in which case GTFO these forums 
If that was long time ago then acquire it and play from the beginning. If it was recently and you really don’t want to go from the start, acquire it and find a savegame from somewhere.
I only play the Source version because subtitles only work with that.
Unless anyone knows how to include subtitles to the original Half Life?
Just get Half-Life 1.
Nicer water effects and a few improved sky boxes are minuscule compared to the massive amount of mods for the original Half-Life.
And physics.
The original is worth getting over Source, though. It may be cheaper, too. I cba to check at the moment.
I too vote for playing Half-Life 1 before playing Black Mesa. I think you’ll enjoy the Black Mesa experience much more, if you’re versed enough in the original to be able to identify all the little nods, improvements, and changes from the original that the devs may have made. I think it’ll be a richer experience being able to witness the huge transition first-hand, rather than playing Black Mesa knowing little more than “this is an improvement of an old 90s game.”
Not only that, but if you play Black Mesa first, you may run the risk of finding it difficult to go back the original, if you decide to try it out later on. I know that for me, at least, it tends to be a lot harder to go back in time with a videogame than it is to go forward. Once you’re exposed to an updated title, it’s just kind of a pain to go back to the original, somehow. Although, you might already be running this risk, since you played through Half-Life 2 already… (Shame on you, by the way! :fffuuu: 
)
I also vote for playing the original rather than the source version of Half-Life 1, due to reasons already mentioned, especially by Grey Acumen and coldroll.
And if you’ve got a mind to play through the entire Half-Life 1 Saga, (Half-Life, Opposing Force, Blue Shift, and Decay,) and not just Half-Life 1, then I absolutely second what Spockjedi said, although I would personally recommend playing through the games in a slightly different order, for reasons I’ll mention shortly.
The order I’d recommend playing them in is: Half-Life, followed by Decay (with a friend, since it’s meant to be co-op) or Blue Shift. Opposing Force should be saved for last, IMHO. Playing either Decay or Blue Shift after having gone through Opposing Force can be somewhat anticlimactic, I think, for reasons I think you’ll discover. 
tl;dr - Yes, play the original (not source) Half-Life 1 before Black Mesa. Also see bullet points above. :3
Isn’t there already an epically long thread about whether or not someone should play Half-Life 1 before Black Mesa, and if so, which version?
Yes.
Not only that, but in terms of in-game time line, Blue Shift actually comes before Opposing Force, while Half Life starts a little before blue shift starts, and theoretically ends a little before Opposing Force ends.
Graphics ain’t everything,bro
Get the original Half-Life and play it for the following reasons which have already been stated and will be restated.
-Better appreciate BM
-MOAR MODS
-A lot of people think HL: S sucks (myself included)
-It will be a good way to pass the time and wait for BM
-HD Pack (for graphics)
-For science
-Runs Better
You’re right. It also has lightly more refined level design, and much better AI.
Founded in 2004, Leakfree.org became one of the first online communities dedicated to Valve’s Source engine development. It is more famously known for the formation of Black Mesa: Source under the 'Leakfree Modification Team' handle in September 2004.
