Wrap it up
The story in some of the series' entries wasn't the easiest to follow. The problem with many of the games were that they just assumed you already had extensive knowledge of the universe, read all of the Halo novels about three times each, had Spartan posters plastered all over your bedroom walls and slept under a Master Chief duvet.
We'd like for Halo 4 to tell a more self-contained story, so those that don't understand every aspect of the fiction can jump in and enjoy a great narrative without having chunks of the plot lost on them.
By all means, include nods and mentions to the books or the past games, but the narrative shouldn't expect you to know every detail of the universe.
It's a new trilogy, so let's start afresh.
