You mean '3' games really focused around the Halo installations. Halo 3 shifted the focus around one, to all of them, seeing as Truth now planned to fire them all, simultaneously. You landed on one at the end, too.
As has already been said, it's called Halo because that's the brand. The whole human-covenant war involved stopping the rings from being fired. They are at the center of the conflict. Reach and Wars took place before the Halo rings became the focus of the war, but then it's all a part of the same lore. They're not gonna change the brand because it doesn't feature any rings. 'Halo' doesn't just mean the rings anymore, it also encompasses the Spartans, Covenant, Forerunner, Shield Worlds; and so on.
