Playground even provided Xbox fans with a number, lending some perspective to what “biggest first week in Xbox history” really means. According to the announcement, more than 10 million players playedForza Horizon 5during its first week of availability. Just for comparison’s sake,Forza Horizon 4was announced to have reached 2 million players in one week. It did reach 10 million players eventually, 8 months after launch.Forza Horizon 4’s 10 million playerswas the most-played game of the Xbox One generation.

A second achievement, impressive on its own but also expected given the franchise’s overall popularity, putsForza Horizon 5at the top ofXbox Game Pass releases, too.Forza Horizon 5had the biggest launch week for any Xbox Game Pass release in the subscription service’s history. These two records, the most-played Xbox Game Pass release and most-played overall Xbox release, are likely to be joined at the hip going forward.

The role of Xbox Game Pass inForza Horizon 5’s launch successcan’t be understated. After all, the announcement was thatForza Horizon 5has 10 million players, not 10 million copies sold. It’s impossible to predict how many copies ofForza Horizon 5Xbox would have sold if it wasn’t on Xbox Game Pass at launch, but it doesn’t really matter anymore, either. Going forward, Xbox’s priority is getting as many people to play its games as possible, whether that’s through full game purchases or via Xbox Game Pass.

It’s difficult to imagineForza Horizon 5being dethroned of its position by any other game at this point, though anything’s possible.Halo’s popularity has waned to a degree, but the live service nature ofHalo Infinitecould certainly boost it to previously unrealized success. Then there’sStarfieldin 2022, Bethesda’s next major single-player RPG.Skyrimsold 30 million copies, after all.

For the time being, however,Forza Horizon 5reigns supreme as Xbox’s most-successful launch ever. Now Playground just has to retain those players, which it’s striving to do with its weekly seasonal content and upcoming Fractures feature. Xbox Game Pass availability makes that easier to do, as well.Playground and Xboxshould definitely take a moment to celebrate such an impressive achievement, too.

Forza Horizon 5is available now on PC, Xbox One, and Xbox Series X/S.
