Ryan Payton has left
343 Industries - the team responsible
Halo 4 - saying the game had become a "crazy endeavour".
Payton, who worked on
Metal Gear Solid 4, was tasked with developing the game's story and overseeing the creative team who were planning the next trilogy of Halo games.
Speaking to
Kotaku, Payton said, "I had a great run at Microsoft. I don't regret one day of it. But after a few years, there came a point where I wasn't creatively excited about the project anymore."
But he took pain to stress that it wasn't because the game was turning out badly. It was simply not in line with his original vision. "The Halo I wanted to build was fundamentally different and I don't think I had built enough credibility to see such a crazy endeavor through.
"I think time is the most valuable thing we have," said Payton, "and I've decided that I'm not going to waste one more day working on something that doesn't speak to my values."
