One of the nice things about the Halo universe is that it welcomes all kinds of fans. Many would rather stick to the games. Some don't even bother with the single player campaigns in those games, preferring to shoot to out in the multiplayer modes and leave the experience at that. But there's a rich mythology driving the Halo games if you choose to dive into it. Increasingly, we're seeing that mythology expand not just in comics and novels, but live-action projects that attempt to show us what an honest, big-budget Halo movie would look like.
