I'm not really sure why it's titled Project Brazil since it has nothing to do with the country at all, but the best guess I can give is because of the sheer scale of the mod. With that said, keep in mind that these aren't only just mods, but they are full-fledged experiences of their own, that come with a whole new story than what you would experience on a normal playthrough of New Vegas. Some of the content creators out there still have some unfinished business left on their projects for Fallout: New Vegas and after 5 years, some of these developers are finally ready to show off their game.
