Red Dead Redemption 2's massive open world is beginning to come into focus. Rockstar Games has updated the game's website to include new information on the "frontier, cities, and towns" that players will find in the upcoming western.

It appears there will be a great diversity of locations in Red Dead Redemption 2. One of the locations is Valentine, in The Heartlands of New Hanover. This is a "raucous, rough-and-tumble town," featuring livestock auctions. These auctions "attract traders, ranchers, cowboys, gamblers, outlaws and prostitutes from far and wide, all looking to make some money, raise some hell, and have a good time."
