It's been a little over a week since Sea of Thieves launched for Xbox One and PC. While it hasn't been completely smooth sailing for the ambitious pirate game so far due to some early server and performance issues, the title is already proving to be a success for Microsoft.

In addition to topping the UK sales chart in its first week on the market, developer Rare revealed that Sea of Thieves is Microsoft's fastest-selling new IP this generation. Moreover, the game has already achieved an impressive milestone, surpassing two million players only a few days after it managed to reach one million in its first 48 hours. That doesn't necessarily mean the game has sold two million copies, however, as it is also free to play for Xbox Game Pass subscribers.
