A specific reason? I dunno… For me, it’s pretty much a mixture of nostalgia and a sucky video card. Besides, you’re not missing much if you play HL1 instead of HLS, unless you want to see guards wearing shiny helmets.
So I continue with HL: S then!
vorts cower in fear
If you already have source, then I wouldn’t buy vanilla. But I would buy vanilla over Source any day. I believe the source version is buggier, and I’m not really a fan of mixing the goldsrc visual style with the source style.
MODS MODS MODS MODS and more MODS!
HL1’s got em’! HL: S… not so much.

HL: S Mods!:
…well… I think someone’s made a few HL: DM: S maps. Is that enough?
Get Half-Life in the Goldsource engine, sure, the source engine has pretty water, and 3d skyboxes, but honestly, you’ll never notice those in game that much.
Another reason you should get the vanilla Half-Life is mods, there’s Sven-coop, paranoia, Natural selection, heart of evil, and many others.
So time to get the game from a friend
This thread is major deja vu
Ya but half-life source has better sound 5.1 surround.
but the sound quality sucks regardless. which is why HL is so amazing.
My word, Play HL original to play the way its meant to be played. And play that alone so that when you play BM, the change would be pleasantly noticeable.
Edit: Yeah i like Playing. 
Oh, and if you are giong to check out Half Life and hate the dated graphics:

And if you will have to stick with HL:Source:

However, this presents you with a nasty point: WIth Daimond’s graphic pack, the original half life actually looks better then Half Life Source with strelok’s improvements.
Both packs do not change the gameplay of the games they are installed on, by the way.
I get the same glitch on every version I’ve played: getting stuck in places. Just the other day, I was replaying “On a Rail”, and got stuck in between the track and the wall. I ended up having to get myself out with the help of a grenade.
And I refuse to quicksave, which isn’t so bad in HL2 when things screw up, because there are frequent autosaves.
The two aren’t comparable. Unreal was just another FPS, albeit a very pretty one, with impressive AI. But it was still just levels which you had to slog through one after the other. On those terms, Unreal wasn’t even an advance on Doom.
Half-Life was completely different. You were now a key participant in a believable scenario, a sprawling research facility on a day that a series of disastrous events gradually unfolded. Your immersion in that scenario was first established in the game’s opening tram ride, where you were just another employee on his way to the lab, complete with comments about your tardiness and a chat with a security guard on the front desk. I hadn’t seen anything like that before. So while in Unreal, it was inconsequential whether you knew your character’s place in the story – you were just playing another shooter afterall – in Half-Life, knowing what you were doing was crucial to your sense of involvement in the world around you.
On this front, both games are as bad as each other: while the goal at the beginning of Half-Life 2 is relatively clear (firstly, get to Kleiner’s lab, then get out of City 17 by the old railroad), you do have similar goals in the beginning of Half-Life 1: get to the test chamber (just follow the signposts), and then get to the surface. On top of that, some levels in Half-Life 1 are just superbly crafted around goals. Take Blast Pit: you need to fire a thruster to kill a huge tentacle beast. You can see that the thruster hasn’t got any power or fuel, but you can see fuel and power lines running down the sides of the chamber to two exits, so you know where you need to go to get things running. My only complaint with this level was the silly use of a giant fan to lift you up to the fuel room.
But most of the time, you don’t have such clues about where you are going. Why the hell am I in this ventilation shaft, other than for the fact that the game designers have set things up so that it is the only possible way to proceed? Incidentally, with the way vents are used throughout the game (which is how they are always used), you develop an unbelievable instinct of saying “Ah, there’s a vent cover. I’ll probably need to go through it at some point.”
I care a lot about the sense of immersion in Half-Life (not everyone does), so these things happen to annoy me a lot. I think it might be the reason that Half-Life has dated much faster for me than other games – in most other games, I don’t care at all immersion. The crappier graphics, physics, AI, and the totally unrealistic first-person movement (back in those days, you moved at 100mph in an FPS), make it a much less believable environment than when I first played it. This is why I’m eagerly anticipating the remake.
^^ Very well said, all of it.
Is that supposed to help me choose!?
It seems I’ll be playing both then :S
I admit, when I first played HL1 I had no idea why I fired a rocket into space, I thought gordon did it for fun and it alerted the military who opened the doors
Play Half-Life.
To be perfectly honest it doesn’t make much difference which you play. Get the original if you think you might like to try out some mods, get Source if you want fancy physics and water, doesn’t matter. Just get one of them and play a classic game. 
Buy the Half Life 1 Anthology. That way you will be able to play the original Half Life, Opposing Force, Blue Shift, and Team Fortress Classic on Steam. It is well worth it seeing that there’s two other mod teams working on an Opposing Force: Source version and a Blue Shift: Source version. That way you can compare all three original games to the Source versions. You should also download the Half Life Decay mod on the Internet. Here are links to the anthology and Decay. By the way Decay was included on the PS2 version of Half Life but not the PC so this Decay mod is the PC version and obviously being a mod is free.
