I'm moving this to its own thread since a few people thought it sounded like a good idea.
I think a petition is in order to politely convince our friends at stardocks to create a play-through commentary a la DVD director's commentary.
Get a few of the key developers (art, AI, design, UI, what have you) in the room and everyone plays through a game and comments on various things that happen, such as why X happens when you do Y or how you arrived at the visual style we're seeing, or how the AI is doing what it's doing.
If I were the one producing this video I'd either have the developers play the game and comment while they're playing, which is spontaneous, but might not lend itself well to commentary because they don't know what's going to happen next. The other way would be to have them play through a 1-2 hour game and then record commentary afterwards.
Would it help if I said pretty please?
