Sea of Thieves is Microsoft's fastest-selling new IP of the Xbox One generation

Rare's jolly old pirate game Sea of Thieves has become Microsoft's fastest-selling new IP of the Xbox One generation, and is already the best-selling Microsoft Studios game on Windows 10. More than a million people played on launch day, and more than 2 million in launch week.

There's a bit of confusion surrounding the wording on Xbox News Wire, where Sea of Thieves is labelled "the fastest-selling first-party new IP of this generation". This suggests Sea of Thieves holds the title across all platforms, which in turn means it outsold Sony's best-selling first-party new IP Horizon: Zero Dawn, which has done incredibly well.

He called Sea of Thieves "our most successful IP of this generation", suggesting the claim relates only to Microsoft's games.
