KeenGamer: “Upon the release of Forza Horizon 5, Playground Games decided to retire Forza Hub completely. This is a huge disadvantage for the loyal fan base, as the app provided so-called ‘loyalty rewards’. Not only do they retire Forza Hub, the entire system of being gifted cars at launch, for playing previous games, may now also be removed.”
