'Forza Horizon 4' reached two million players in its first week.
Microsoft has announced that the new racing title hit the impressive milestone during its launch week on Xbox One and PC.
In a press release, the company said: "It has been one week since we launched 'Forza Horizon 4' and we are humbled by the overwhelmingly positive feedback we continue to receive from players around the world.
"We are proud to say that in this first week alone, there are currently two million players driving around Forza Horizon 4's Britain.
"On behalf of everyone at Playground Games, thank you for supporting 'Forza Horizon 4' and making the game such a success!"
The company also revealed that players have already collectively driven more than 822.7 million miles, with the community buying "more than 4.1 million properties and owning more than 74.4 million cars".
Microsoft hasn't revealed how the two million figure breaks down between outright sales and people playing using their Xbox Game Pass, or whether it includes people playing the free demo.
Also in the announcement, it was noted that the highly anticipated Route Creator feature will launch free for all players on October 25.
This will allow gamers to drive wherever they want - on the road or otherwise - to create a route, ropping checkpoints anywhere before sharing it with other users.
