Changing the language in Hearts of Iron IV (HOI4) is straightforward and can be done through the game launcher or Steam settings. Method 1: Using the Paradox Launcher
If your native language is not officially supported by Paradox (such as Chinese, Turkish, or Italian), the HoI4 modding community has created extensive translation mods. Go to the Steam Workshop for Hearts of Iron IV.
