EU4's Interface, also called user interface (UI), or graphical user interface (GUI), has a number of specific screens and visual elements. This article will focus on the pragmatic purpose and utility of the interface (as opposed to the stylistic elements).
The EU4 game launcher is used to launch the game and handle all pre-game options.
The launcher is separated into the following:
- News tab.
- DLC tab – lists all available DLCs sorted by type and quick enable/disable.
- Mods tab – lists all available mods and quick enable/disable.
- Paradox account – used to login into PDX account if one wishes to use features such as leader-boards, etc.
- Play and the option to continue the last save
The main menu is the first screen players see after the game loads at start up, and where players return to after they leave their in-progress games. It (usually) shows a map of continental Europe along with some tool bars, buttons and information along the bottom.

If you start a new game you will be presented a screen that tells you what's happening in your country. It will help introduce the mechanics available to your nation and explain some of the more important nuances about the country.
It is divided into 4 parts:
- Country - On this place is a background story about the past of your nation, and the neighbors.
- Religion - Here you will learn about your faith's mechanics and boosts. Also there are explanations about DLC features that changes your religion (it will be marked with the DLC's symbol).
- Government - Here you can see what type of government you have, and if it has any special features.
- Environment - Explanation about big diplomatic actions or mechanics for the region. Like the HRE in West-Europe, or tributaries in East-Asia.
