Updated on August 02, 2025, by Ritwik Mitra:New Vegas is a game that many people consider to be the greatest Fallout game ever made, which is high praise indeed. Obsidian Entertainment knocked it out of the park with this title, but not all was sunshine and roses with this title’s release. Despite its amazing role-playing systems, the lack of stability and a bevy of glitches in the title posed several issues for this game at the time of launch, and most people would agree that playing this game without modern mods to mitigate the crashes and problems present in this title is downright necessary to enjoy the experience. Players who want to check out this title after the bombastic Fallout TV series ended its run will love the many mods they can use to make the game as stable as possible.
