And he completely missed part of the big picture. Like, how the main reason that Bungie decided to use multiple races as ememies was because, unlike just fighting humans, they are more interesting? That's what Bob started out on, but he missed the point that the reason that the Covenant are so cool to fight is because there is a bigger variety. I've heard people say that they would play Halo if there was a story where you could be the Covenant fighting the Humans, but that would just be boring. Then you would be basicly playing Modern Warfare 2's multiplayer with a mode that makes you look like a Grunt or Jackle!
And For the record, I never even had an X-Box Live acount until I bought Reach, and I bought ALL of the Halo games, just because it had an awsome story and campaign. Plus I got all of the books I could find. So maybe I'm just weird, but Online Multiplayer, in any game, isn't a big deal for me. Split-Screen is another story.
