Forza Horizon 4 is an open-world driving game from Playground Games. It is set in the United Kingdom and builds on most of the previous concepts found in the previous installments of the Horizon side of Microsoft's long-running Forza franchise.
Unlike previous entries, Forza Horizon 4 is a connected game, with human players surfacing directly in each other's open worlds instead of the "drivatar" AI found previously. The game has a focus on weather and seasons, with each week changing between the four seasons. In winter, the world will be snowy, rain falls in the spring and autumn, and so on.
