Xbox boss Phil Spencer recently said he believes the modern Microsoft ecosystem may have enabled the company to retain Halo and Destiny creator Bungie.
The studio was acquired by Microsoft in 2000 ahead the original Halo’s release but split from Xbox in 2007.
Speaking to Axios, Spencer said he understood why Bungie wanted to leave Microsoft, even if it meant relinquishing the Halo IP.
“At the time they had big ambitions. They had sold their business for a certain amount of money. They saw what Halo turned into. And it’s like, ‘OK, Microsoft benefited more than Bungie did from the success of Halo.’ There’s no other story that can be written there.
“If you’re saying, ‘Hey, I think I’ve got another one of those in me. I want to really take another chance,’ I can understand the allure of doing that as an independent company.”
When asked if he thought the split from Microsoft was inevitable, or if Xbox could have held on to Bungie, Spencer responded: “Could we do it today? I think we could.”
