Microsoft studio developers will work together more often says Phil Spencer

During an interview with Stevivor last month in Australia, Head of Xbox, Phil Spencer stated that Microsoft Game Studios development houses will work together on certain projects, but not at the scale of Ubisoft and EA.
Some fans have noticed the water in Forza Horizon 3 looks very similar to Sea of Thieves style and thought that Playground and Rare teamed up on that, but Phil declined to comment.

With Forza Horizon III I think the great example we do have is the Turn 10 Team, which is in Redmond, Washington, and the Playground Team, which is in Leamington Spa in the UK. Turn 10 works on Forza Motorsport and Playground works on Forza Horizon, but they use a shared engine and pipeline. The technology advances that they make together, iteratively, as they launch each one of the franchises leads to a better product for both. It’s fantastic, because the technology advances faster.
Somebody’s doing multiplayer, somebody’s doing single-player, somebody else might be doing co-op. Big triple-A games are now massive budgets. They’re on the scale of a blockbuster movie. First-party, we’re shipping on fewer platforms. For us, we’re shipping on Xbox and Windows.
“The idea that we would engage a thousand developers to go work on a first party game is probably not where we are. We probably choose things that we think are more linked to the platform work that we do. We want to make them big. Gears of War will be a huge game. Halo is a huge game. We’re doing really well with Forza Horizon. The idea that we’d have multiple studios pivot, I think, is probably more of a third-party thing just given the scale and the surface area that they ship into.”

This is a great idea for Microsoft to do this because every title has something unique about it and why not spread it around.
