I think it might be 2002-2011? Or maybe 2003-2012? It's a weird choice in any event.

Now I hardly say this because of the responses, but I dont care much for Half Life story. The gameplay is solid in all respects, but I just think the story is lazy.

Only Nintendo can pull off the silent hero. In a sci-fi PFS, a silent hero is just lazy. Its all overly vague and mysterious with Gman. Thats ok, but some answers should eventually come out. You still have no idea whats going on in the broader scope of things.

With Halo, it gradually tells you about the universe. You learn of the Forerunners and Covenant in Halo 1. Halo 2 gives you a view into Covenant society, so now we understand them. The other Halos expand upon this. Foreunners are largely a mystery to us for years, giving us only bits about their culture and technology. Only recently have we learned far more about them with Halo 4 and the Forerunner Novel Trilogy. Master Chief also speaks. Not much, but he speaks. The novels tell you all about him and Halo 4 starts to bring out the more human attributes in him. Gordon not speaking at this point seems....lazy.

If the lore and universe remains vague too long, it just means the developer doesn't know where to take the story, or doesn't care.

They play for the gameplay above all else im sure. Like how millions play Halo only for the MP.

By pull off I dont mean sales (in which case Valve pulled it off). I mean story-wise.

Can you try to address the legitimate story complaints I talked about before. I love sci-fi, but I could never get into that universe because of those reasons mentioned above. I think the next Half Life Valve has to step up their game with stroytelling. Gordon has to speak (this isn't the early 2000s anymore) and the major lore plotholes have to be filled in IMO.

Guess its just one of those anamolies in gaming. Personallhy, if Im gonna go the silent protagionist route, Id say Bioshock 1 and Dead Space 1 outperformed Half Life 2 in story and physics gameplay. Yes I know Dead Space is 3rd person. But nm, I said my origional piece. Guess it just isn't for me.

Pezus the best thing to do when you don't know about a game is to stay quiet because your comment on metroid prime is shooting yourself in the foot.

you do realize I could half life is irrelevant because the only people who know are the very hardcore as mainstream probably didn't even know it existed until it said on t.v. Hell I guess every halo makes half life a forgettable trash game. 

  Yes it is

15mil. on how many platforms ? :S

From memory, around 9 million on PC/Steam and the rest divided amongst the consoles (Xbox + 360 & PS3 if they count Orange Box).

I suspect he's trolling you.
