A high Strength can help raise your lowered carry weight, and high Intelligence will ensure that you gain more skill points upon leveling up. Rather, invest your points in more concrete statistics, like Strength or Intelligence. High Charisma is a dreadful waste of SPECIAL points, and will get the player nowhere. To begin, take all of your SPECIAL points out of Charisma. Plan accordingly when creating your character.
This is a true wasteland, where almost everyone you encounter is keen on killing you and taking your equipment, or worse. This isn’t your neighborly Vegas paradise. A high-Speech, high-Barter, high-Charisma playstyle will almost certainly result in the player having a very difficult time playing Dust. Character creation in Dust should not be handled exactly as one would in vanilla New Vegas.
