Although they aren't, technically speaking, Halo story canon, the thematic and verbal similarities between the recent Halo 3 trailer and the Cortana Letters from 1999 have resparked interest in the latter; TraxusIV has embarked on an ongoing series of analytical articles that look at those themes and put the Letters into the greater context of the Bungieverse, past and present. The newest article looks at the second letter.

1Up has a Bungie retrospective up, covering in detail Pathways into Darkness, the Marathon trilogy, and Halo 1, with a tip of the hat to earlier games as well. Interestingly, the Bungie-published but not developed side-scroller Abuse gets a mention, while the numerous Marathon licensees and the unmentionable Weekend Warrior do not. Thanks Louis Wu at HBO.
