Fallout: New Vegas is an action role-playing game developed by Obsidian Entertainment and published by Bethesda Softworks. Released in 2010, it is the fourth main game in the Fallout series and takes place four years after the events of Fallout 3. The game is set in a post-apocalyptic Las Vegas and the wider Mojave Desert, offering players a vast open world to explore.
Solution: The SiMON repack places DLC .esm files in the Data folder, but they may not be activated.
As Fallout: New Vegas is an older game (released 2010), running it on modern systems (Windows 10/11) often requires tweaks, regardless of which repack you use.
