As a campaign-only Halo player, the complains are a bit disappointing, as the story doesn't seem to be as good as it was promised. The fact that the game heavily relies on lore and story content not found in previous games, and doesn't explain it (forcing you to rely on those outside sources instead of the games themselves) is terrible (if certain reviews that point this out are to be trusted).
I can understand expanding the lore outside the games, but the people like me who only play the games shouldn't be left hanging because of it. That's weak storytelling, as far as the games are concerned. As much as I love the game, Gears of War 3 pulled out the same thing and I wasn't happy.
