RDR is set in the Wild West, and you can visit a fictinal part of Mexico later in the game. While there, the locals usually call your character "gringo". Since your username has "wild " and "gringo" in it, I just kinda connected it with RDR. By the way, you really shoud play it. It's like GTA set during the 1910s in the American West (made by the same studio that does GTA) and it got solid reviews from both players and game rating companies. It's a hell of a lot better than Destiny, and since it's 6 years old, quite cheap too.
