Well-known Bungie fan vector40 has written a review of Halo for The Junkyard:

Now, let me start by saying this: Halo has a level of hype surrounding it that you'd have to go back to Daikatana to match. The main worry of most fans (and, presumably, of Bungie itself) is that the hype will surpass the game, as has happened in the past, and no matter how good the game ends up, people will be left disappointed.

Wrong.

Sounds like he liked it. Thanks to Louis Wu at HBO for the heads-up story.
