In Fallout 3, stuff like your strength and intelligence didn't make a whole lot of difference outside of skill checks, learning perks and other purely mechanical aspects. The team behind Fallout: New Vegas took the time to expand on this aspect though, with some hilariously ridiculous results. If you want a truly unique experience while navigating the Mojave wasteland, then try creating a character with just one point in their intelligence stat. As well as making your character terrible at science and medicine, they'll also be incapable of talking properly, while most of the NPCs you come across will treat you as if you're mentally deficient. Many of the dialogue options are extremely funny, often consisting of just a few disconnected words and grunts.
