*Pothead voice* Didn't you hear man? Robots/cyborgs don't have emotions! They aren't human!!!
Seriously though, I haven't played the game so I can't agree/disagree with you but his voice does make it seem that way.
Why is everyone so happy when they see Gordon Freeman?
I am NOT ready to be flamed for this but.............. I don't understand why people love Half-Life so much. Granted, I never played the games, buuuuuut, I did watch the walkthroughs for it on YouTube and it never struck me as something special. I had Half-Life when I was a kid but back then, I never played games unless it was my Super Nintendo. Back to my statement though, I liked Alyx but I felt like people give Gordon too much credit. First off, i can hardly stand silent protagonists either and like you said, he doesn't do much except smack people with crowbars in the face. Half-Life 2 didn't seem like a godly game everyone think it is imo. The gunplay seemed very bland and the assault rifles bullet sound is terrible and the ammo for each clip/magazine/whatever runs out quick. I don't feel like writing off everything I dislike about the game so I'll go onto the pros.
The story was rather interesting as well as the characters. The environments were great and the enemies had interesting designs, I'm talking about aliens though. I like how Aperture is the main goal for the humans because their science and stuff. I don't know what else. I saw the walkthrough a couple months back so I don't remember.
All in all, the game seemed good to me, at it's best. So I don't understand why everyone loves it so much.
