Forza Horizon 4

Forza Horizon 4 features over 450 licensed cars. It includes a route creator which enables players to create their own races. The game takes place in a synchronised shared world, compared to the AI-driven Drivatars from its predecessors, with each server supporting up to 72 players.
 The game is also playable in offline mode.

Players have the opportunity to buy properties from across the map, which unlock new items and gameplay perks. The game features a dynamic weather system that also depicts the change of season. The game world changes depending on the season: for example, lakes will freeze over in winter and allow players the ability to explore regions of the game world that would be inaccessible during other seasons. The seasons are fixed across the game's servers, meaning that all players will experience the same conditions at the same time.

Playground Games have also announced plans for two downloadable content expansion packs for the game.
