This is an 'umbrella term' that includes everything from the game launcher options and hardware configuration Menus, through the loading screens and 'Main' & 'Pause' Menus, and into the information you see on the screen when the game is loaded (referred to as the ' Heads Up Display' (HUD)), and the Menus provided in the Pipboy, when trading, etc. The way the player interacts with the game is through something collectively called the ' User Interface' (UI). 7.7.1 Personal UI Menu Overrides Package.7.4 The Mod Configuration Manager aka MCM.7 Technical Details for Manual Installers.
