Wait... Are you saying that you are not satisfied with Halo 4, or Halo in general? Halo 4 is not the best I'll admit, but 343i apologized, Hired Bravo, released CSR, created Forge Island exactly the way forgers wanted since Halo 3 and they released it for free, they also made over Five Title Updates, over six monthly updates, and countless weekly updates, plus they did the weapon tuning according to the small feedback from the minority of the Halo community on the Waypoint Forums, now they are considering doing Spartan Ops Season 2, and making more DLC, plus they promised to do way better in Halo 5, so please don't give up on Halo just yet...
If you made Halo 4 and no one liked it, but you knew how to make Halo 5 the best game ever, would you want fans to give up on you on your FIRST attempt at making a Halo game? Give 343 a chance to redeem themselves.
