Hot saving, also known as quick saving or manual saving, is a feature in many games that allows players to save their progress at any time. This feature is essential in games like Forza Horizon 1, where players invest a significant amount of time and effort into completing events, collecting cars, and upgrading their vehicles. Hot saving enables players to save their progress quickly and easily, ensuring that they do not lose their hard-earned progress in case of an unexpected interruption or a game crash.
