It was a mod in The Elder Scrolls that added new quests to the civil war between the Stormcloaks and the Imperials. One of the most popular Skyrim mods was called Civil War Overhaul. Mods are keeping the game alive apart from the long main story.
These changes can range from simple things like changing the colour of something to an entirely new game mode within the game world. A mod is an alteration by players or fans of a video game that changes one or more aspects of a video game, such as how it looks or behaves. This is one of the most modded games released by Bethesda. Many changes are to be made in the game’s appearance, visual quality, adding storyline, new factions, and gameplay mechanisms.
A lot of people are still working together to improve the game.
