On what date was Forza Horizon 4 released for Windows and Xbox One?

Forza Horizon 4 was released for Windows and Xbox One on 2 October 2018.

Playground Games and Microsoft announced the game at Xbox’s E3 2018 conference. The standard and Deluxe editions launched on 2 October, making that the ordinary release date for both listed platforms.

The Ultimate Edition caused some confusion because it provided earlier access on 28 September 2018. That was an early-access date, not the main release date. Likewise, 10 November 2020 refers to the later Xbox Series X/S version, while 9 March 2021 is the Steam release date.

Forza Horizon 4 followed Forza Horizon 3 and shifted the festival to a fictionalised version of Great Britain. It also introduced the series’ changing-season system, with spring, summer, autumn and winter altering the scenery and driving conditions.
