Fallout New Vegas is more of a Modded Fallout 3, than an actual Sequel. It uses the same engine and game mechanics, only adding/removing a few features and set it in an other region. If you only play Battlefield/Call of Duty/FIFA and the like, youmay call FO:NV Fallout 4. But if you actually know some real games, you'd know that it's no sequel.
