Halo - what's so great about it?

[Hammer-of-Dawn]

Halo made the xbox launch a success

halo 2 saved LIVE from failure

Halo 3 raised the bar for accessable, addicting, and deep multiplayer.

SOme may disagree but from a sci-fi perspective, the story is top-notch, especially if you factor in the 6 well crafted novels.
