All that changed when the prisoners of the NCRCF broke out in late 2281 and started wreaking havoc.
Unlike its neighbor, Nipton, it also had an effective sheriff. For all who couldn't or wouldn't want to reach New Vegas, it offered a casino, hotel, several shops and a courier waystation. In the late 23rd century, as the NCR expanded into the Mojave, it suddenly became a promising trade town, benefiting from the growing traffic to and from New Vegas, both civilian and military. It developed a small, tightly-knit community over time. The town lost much of its appeal after the Great War, as survivors and then wastelanders had other concerns. The resort had a number of tourist attractions to boost its appeal, including the Vikki and Vance Casino, dedicated to a pair of outlaws who were the southwest answer to Bonnie and Clyde, and the Bison Steve Casino and Hotel, with the Mojave's largest and most rickety rollercoaster, El Diablo.
Quickly becoming known as a budget version of the latter, Primm allowed tourists from California to get a taste of the city of sin on the way in or lose what remained of their savings on the way out.
Before the Great War, Primm was a small resort town located in Clark County, Nevada, sitting alongside Interstate 15 connecting Los Angeles and Las Vegas.
