i just don't understand what all the fuss is about in regards to introducing plot points to fill in the gap for non lore folks, if you really cared about the story in any of the halo campaigns then you would pick up the books, as well as comics and keep up to date with the halo world, if your not that interested then just run through the campaign and enjoy the action
I could not disagree more here. I have been a Halo fan for a long ass time, love the campaigns and am generally engaged with what is happening in the story, but have little interest or time to explore the lore outside of the games. Thus, it's always appreciated when the story is primarily contained within the campaign.
