Meh, Duke’s was Okay, but it got tiresome after a while. I could only take about 2 "heh, heh, heh, waht a mess!"s before I turned the sound off.
Gordon freeman doesn’t have to say anything, he is the game.
DAMMIT!,I lost.
GORDON ISN’T MUTE!!11!11!111ONE!11!1!
Whenever you take fire damage in HL2, he makes a quiet hissing sound. 
Plus for a job at black mesa he used a phone at one point. https://en.wikipedia.org/wiki/File:FreemanJobLetter.jpg
HE ISN’T MUTE.
If Gordon was autistic then he would have just locked himself in his locker and made a line of his belongings going from bigger to smaller during the resonance cascade
But seriously, Apparently Bill gates and Albert einstein display traits of autism and they were/are pretty smart/successful. I guess gordon could be autistic…
But down syndrome? no way…
Alyx ‘‘Gordon! watch out! Combine!’’
Gordon: ‘‘ARG A FUFU WEEEEEEEEE :retard:’’
So Deaf people can’t talk?
Fuck you, you twat.
well someone woke up on the wrong side of their mother…
He’s just being a retard, no need to call him a twat, we’ve already established he’s far more than that :3
Mute people can use phones.
Just sayin’…
Autistic people have compatibility issues with cubemaps.
His locker is already well organised in Half-Life. He doesn’t speak and can’t easily communicate with people and yet is vastly intelligent and impeccable at solving complex problems. All the friendly NPC’s patronise and praise him.
Gman also shows traits of autism.
Yeah, so do I, what’s your point?*
Just because someone shows traits of a disorder doesn’t mean they have it.
*Actually, I was diagnosed with Aspergers Syndrome, but it either cured itself of the doctors were wrong.
Footnote edit:
That explains it, I guess.
After Alyx Vance tells her father “Prepare for unforeseen consequences,” in HL2: E2, Eli Vance informs Gordon that those were the same words he (Gordon) told him before entering the Anomalous Materials Test Chamber.
As a video-game player, you do not hear Gordon Freeman communicate because there is no ‘official’ voice of Gordon Freeman, for this being a factor of Half-Life publicity. End of story.
Hearing [COLOR=‘DarkOrange’]Gordon Freeman’s voice is equivalent to revealing [COLOR=‘Green’]Master Chief’s face.
What the Crap?
…
Please edit your post next time.
No. It’s the words he (G-man) told him. Gordon didn’t say anything that morning.
Sweet mother of god.
Gordon not talking is a gameplay device. It has no bearing on the story whatsoever.
Gordon’s talking is purposefuly omitted by valve just to make fans, like the OP, ask why he doesn’t talk.
EDIT
I’ve always thought that if Gordon Freeman HAD a voice, it would be so interspersed with Expletives, ESRB would prolly object.
He’d go from
"Heh, heh, sorry I’m late. Overslept… Again… 
"
to
“HOLY SHIT WHAT THE FUCK IS THAT MOTHERFUCKING THING?!”
Now that’s going to be in my sig.
ACtually, Gordon does speak!
I was playing HL1 today, and a headcrab jumped on me or something, I dont remember. It was on the slanty elevator near the beginning, you know with the headcrabs jumping down from above, the water pit down below and the houndeye that appears in the box and the…
Sigh. ON this thing.
Gordon made a ‘Gmrgahh’ sound when one jumped on me.
So he can make noise!
In HL2, he hisses when you step in fire.
