So what are your favorite things about the half-life universe?

Personally I just can't get enough of the story.  I don't know what it is but there is something I find so interesting and intriguing about every single part of this series.  Some of the characters that have been created are so interesting and have really been deepening the mystery of whats really going on(who/what the hell is the g-man?!).

So lets hear it, what are your favorite things?

I totally agree with you... The story is awesome. Although when you tell it to someone who didn't play the game, it sounds very silly. For this reason, I think the story telling aspect is just brilliant.

My favorite thing in Half-Life got to be Freeman himself; A PhD graduate from MIT, and at the same time, a bad ass who is good at shooting aliens, and dudes in the face. How awesome is that!!

I like the look

Graphics, gravity gun and story.

Yeah telling the story to someone who hasn't played the game makes it sound dumb lol.  But once you actually play the game and see how the story unfolds and how it's told, becomes a completely different experience.    Also I think the way the game plays is great, for instance I can't stand the halo games because I just feel like there is something missing in the way the game plays, it's hard to explain...

Definitely the story, and the story-telling.  The characters are just flat-out amazing - especially Alyx ;)
