No, I think they had done all they could with it by Reach. It was pretty clear they didn't have much left for it by then, too. It's like any project, there's only so much that you can do with it before you move on. I'm glad they started something different instead of trying to milk Halo for everything it's worth. I mean, that's what got Nintendo into the position it's in right now. They just remake the same games over and over again, so no one really cares about any other games they might make. They just want the old standbys. Or worse, they stop caring altogether. You need to change and do new things if you want to grow and stay afloat as a company.
