Right, obviously since I didn't read the Halo novels, it means I don't read novels at all.
I know how a story should be told, and what I'm telling you is that the story in ODST is more personal, more interesting, and better told than the previous entries in the series. The novels have NOTHING to do with it. This is a video game, a completely different medium with completely different storytelling requirements. I have no idea what you mean by "puzzles" because the only puzzles I saw in ODST were "how do I kill this guy the best?"
By night time, the Covenant had completely secured the entire city. Why would you think that they WOULDN'T remove bodies from the streets, when they're an extremely religious alliance (meaning they would have burial rites for their dead), and even the human bodies would do nothing but get in the way? The audio logs were alright, but honestly whoever voiced Sadie is just abysmal, and I couldn't stand listening to her rabble on about nonsense I had no reason to care about.
I get the feeling you wouldn't like Firefly either.
