"Before leaving the house we may also choose our first Trait, an extra character-defining quality not offered in 2008's Fallout 3. Some of these have pros and cons. For example, "Four Eyes" would give us plus-one to our perception if we wear glasses, minus-one if we don't. An odder one, Weird Wild Wasteland, would turn a lot of the game's cheekier jokes on or off. For example, you can play New Vegas with a willingness to come across a refrigerator that contains a bullwhip and hat — or you can play without worrying about seeing them. The jokes are an homage to Fallout 2, which was also full of pop-culture references to the delight of some fans and the consternation of others."
