I really
don't understand the Halo hype. At all. I've played the second and third games, single- and multiplayer, at a friend's house. They're really nothing to write home about. More of an exercise in stunning mediocrity and unoriginality of ideas that have been done years before both in the sci-fi genre and in the FPS genre....
To condense all of my Halo-related feelings to one entertaining image...
Methinks you're not looking hard enough
