hah, you gave Searchlight Airport a use, you gave it an army of gnomes.
Yeah, the gnomes are planning their take-over of the Mojave after all of the other factions have killed each other off. Some of them are armed and some of them are, well, not so armed.
And speaking of lists of useless things, here's another useless list for you Emma, if you're listening. What about the nearly empty locations in FONV, like Searchlight Airport? (this is not really a criticism - I love this game). But can you imagine you are on the development team and you are given the assignment to create a huge expansive airport location and decide to fill it up with . . . nothing. No building to enter, no people, only two chests to open, a coupla radscorpions to kill. Nothing. Could have at least put in an army of gnomes. . .
I'll start the list for you
Searchlight Airport
most underwater locations (beautifully done, but nothing there)
