According to one gaming analyst, the best-selling new PlayStation 5 game based on copies sold is Microsoft’s Forza Horizon 5. Microsoft launched the game on PS5 at the end of March this year, and it recently eclipsed 3 million copies sold on PS5 to become the console’s best-selling game of 2025, according to Alinea.

The research company said the recent sale on Forza Horizon 5 on PS5, which brought the price down to $45, helped the game surpass 3 million sales on Sony’s platform.

Alinea added that Forza Horizon 5 is a juggernaut on Xbox, reaching more than 45 million players on Xbox One and Xbox Series X|S through sales and Game Pass downloads. The game is reportedly performing well on Steam, too, reaching 6.5 million copies sold, Alinea said.

The company further predicted that the inevitable Forza Horizon 6 will launch on PS5 on day one. Microsoft has not announced any new Forza Horizon games, however.

Alinea’s report went on to claim that the PS5 and Steam versions of Forza Horizon 5 have generated nearly $400 million in revenue. The research firm said Microsoft’s ongoing strategy to release its games on other platforms is part of the company’s transition “from a console platform holder to a third-party publisher.” Microsoft is not getting out of the hardware business, though, having already confirmed it’s making a new hardware platform with AMD. However, Alinea said the company’s next system “won’t really be a console,” but instead could be a “console-like gaming hardware project.”

“Microsoft probably won’t market the next Xbox as a PC, but in functionality, it will likely get closer than ever–a console that runs like a PC, integrates deeply with Windows, and supports cloud/hybrid gaming,” Alinea said.

Microsoft has partnered with Asus for the Xbox Rog Ally line of portable systems launching this year. Microsoft was at one point reportedly considering launching its own Xbox device, but that’s no longer the plan, it seems.
