The Forza series
Forza is a series of simulation racing games consisting of two ongoing titles: Forza Motorsport and Forza Horizon. The former focuses primarily on professional-style track racing events, whereas the latter is set in a fictional racing and music festival - the Horizon Festival - an open world inspired by the real-life areas. Forza Horizon 5 is the fifth installment to the Forza Horizon title and the 12th main installment to the whole franchise. This time the players find themselves racing through the diverse landscapes of Mexico. 
The Horizon Adventure
Forza Horizon 5 takes you to the vibrant and constantly evolving settings of Mexico. Take limitless drives through the ever-changing environment of the map. Explore various landscapes the game has to offer, such as deserts, jungles, historic cities, ancient ruins, picturesque canyons, and beaches, or have a go at reaching the top of the volcano. 
What makes the races unique are the dynamically changing weather conditions, including dust, snow, and rainstorms. 
An evolving world
Forza Horizon 5 features more cars than ever before, with several vehicles making their debut in the franchise! There are also new characters that you can engage in the Horizon Story missions and take hundreds of rewarding challenges.  
The game allows you to join other players in the Horizon Arcade, a series of challenges that will keep you entertained for hours! You can also meet new players in Horizon Open and Tours. Forza Horizon truly is a social world in which you can share and have fun with other race enthusiasts.
