I saw this idea posted over at Bethesdas forums and I thought it was pretty good. If Obsidian could return to Fallout New Vegas, convert it to the new Fallout 4 creation engine aswell as add features to Fallout New Vegas that originally had to be cut due to time restrictions during development. We would get a better Naw Vegas and Obsidian might be able to bring back traits and skills to the new engine. Pros: *New Vegas would be a better game with the new weapons customization feature and better combat of Fallout 4 among other thing. *If Obsidian could bring back traits and skills to the new game engine that would benefit the mod scene. Cons: ?
