Needless to say, picking one game over the others is not an easy task. They all have their strong aspects while only a few have shortcomings. Meaning that even a game ranked last of the bunch from a certain point of view still doesn't necessarily lack in that area; the others just do it even better. (A very good example of this would be the music.)

Still, I'll have to give my vote to Halo: CE for bringing all of the series' key components, an excellent story and immersion unlike anything else at the time.
