Related: Here's Why Bethesda Still Needs Fallout: New Vegas 2 With fleshed-out story-lines featuring fully-voiced questlines, this mod weighs in at 40GB, making it bigger than many official DLCs that Bethesda has released.

The mod also adds more than 100 new weapons and drivable vehicles, this being the first time players can actually drive vehicles in any Fallout game apart from the tank-like armor in Fallout 4. Called The Frontier, it takes place in the snowy wasteland of Portland, Oregon, whose map is as big as the Capital Wasteland of Fallout 3. The massive mod that has been in development for 5 years adds 35 hours of gameplay. Various mods have been created by passionate fans that have improved on the game or added more content for fans who can't get enough of the game, but a huge mod that fans have been looking forward to for years was recently taken down due to a discreditable action from one of its developers.

Even after Bethesda has released newer Fallout games, New Vegas remains a fan-favorite. Fallout: New Vegas was a unanimously agreed upon hit when it came out in 2010, and still reigns supreme as the best Fallout game of the franchise.
