Which is a pretty big deal really. Forza Horizon 4 is a massive title, and so is the series on the whole, so to have existed up until now in the PC space without ever having been available on the most popular PC platform in Steam sounds strange when said out loud, but has finally been rectified as of today.

We've held this series in very high regard for a long time, and can't recommend it enough as far as open-world gaming goes, as well as racing. And obviously the marriage of the two is what stands out best here.

As well as being available on Steam, the new release joins the cross-play party, allowing players across the Xbox family of devices and Windows 10 PC to be able to play together with Steam players. But enough from us, here's the official word from creative director, Mike Brown:

Last month we announced Forza Horizon 4 was headed to Steam for the first time, and today we welcome new players as Forza Horizon 4 is officially available for purchase. We’re excited for Steam players to experience the joys of driving in beautiful, historic Britain alongside players across Xbox Series X|S, Xbox One, Windows 10 PCs and cloud gaming with Xbox Game Pass Ultimate.
