But in that time, I've never seen something quite as ambitious as Fallout: The Frontier, a mod that took seven years to develop and that basically adds an entirely new game experience into Fallout: New Vegas. I've been a close follower of the Fallout modding scene for years now, and I've seen some truly incredible mods release that breathe new life into these older games. Some have even created mods for the online MMO Fallout 76. The Fallout franchise has been a favorite for modders to play around with for over a decade now, with thousands of different creators investing countless hours into projects for Fallout 3, Fallout: New Vegas, and Fallout 4.
