Out of Microsoft’s first party titles, Forza Horizon 4 is certainly the most anticipated one right now. The third installment already garnered widespread acclaim and developer Playground Games is looking to build on that by expanding the feature set and delivering a stunning British backdrop to the game.

Speaking with GamesIndustry at Gamescom 2018, Aaron Greenberg (Global Product Marketing Manager of Xbox) said that the expectation is for Forza Horizon 4 to become the biggest and best-selling title ever in the Forza franchise.
