What I was trying to say is I don't understand why the OP is mad about Hollywood copying the story. Half Life the movie may be trash or it may not, maybe a lot of non-game players will love it! A hell of a lot of non-bookworms loved Lord of the Rings when it made it to the film medium that would never have considered the story in written form. I'm sure this will be similar, though I can't guess the films success or qualities until I at least see a trailer. Even if it is terrible though, it's hard to believe that OP's memory of the game will truly be tainted by the film.
If the aim of a story is to deeply immerse the reader, listener, watcher or player into it then games should theoretically be superior. Of course this isn't always the reality. I watched someone else play The Last of Us, I wasn't the player and I've never played it, yet I enjoyed watching it be played more than most of the games I've played in the last 15 years or so of gaming. I'm convinced it would make a good film or short series because of that, I'm certain it would if they made it a computer animated film and kept the original voice acting and score.
