I remember talking to a game journalist about the difference between interviewing AAA developers and indies. He said a lot of indies and academics never stop talking, but AAA developers get quieter much faster -- maybe they were trained by PR or maybe they're tired? who knows -- but the most recent exception was an interview with a Far Cry 3 dev. This was back in August, so I was thinking, "oh yeah Far Cry 3, they're making that huh," and listened.
He said the Far Cry 3 interview was interesting because apparently the writers did a lot of research on insanity. They wanted to deconstruct insanity. They even featured an insane NPC as the character in the cover art, not the player character / protagonist, which was probably the first sign of them overestimating the importance (or, player interest) in all these details.
"But how do you explain insanity in rational terms?" I asked, "and I saw the trailer, it just looks like -"
The journalist nodded, "yeah, I know."
(Unrelated to insanity: this strange interview with the Far Cry 3 writer.)
