LOL don't make me laugh...
Halo is nowhere near the international phenomena known as Star Wars...not even close. One is a videogame series which spawned off some novels whereas the other is a premiere movie franchise which also sold several bestseller novels (hard to believe but ok) and actually have their own videogame franchise.
If Halo is to be compared to any movie franchise, it would have to be Rambo. Not known for its story, but hella entertaining.
