Halo 4's development sounded like it was quite disjointed, and to be honest you can tell in the finished product. Working with a 300+ team was probably very difficult. I hope they learn from their experience.
This quote really stuck out to me:
"It's during that time you're questioning yourself: 'How is this going to work, will it be as I envision it in my head?" says Holmes. For Halo 4, he says there were a few epiphany moments that helped boost the morale of the team. One of the earlier ones that Holmes recalls was when the team completed a small piece of the Halo experience that he described as a "very traditional" Halo. User research showed that people thought it was a lot of fun, and it showed that the team was capable of making a Halo game that was true to what the series was about.
343 scrapped it, Holmes says, as it was too traditional. But that first build showed the new team that this amalgamation of different studio cultures could work together and achieve a common goal.
