I really hope that Bungie isn't actually aiming for a rating. I've heard that they are, but I'm hoping that's just a rumor or something, because they need to just make the game they want to make and do whatever it takes to make that happen. Whether that takes heavy themes or gore or language, whatever. However, if all of that is unnecessary for this game, that's fine. I mean, I started playing Halo:CE with my dad when I was 10 in co-op. I totally see the appeal of the game being accessible to as many people as possible. So long as that doesn't impact it negatively, the rating could be E for all I care.
