Its restrictive because Bethesda has no creativity anymore. A lot of the old ideas cor the world back around the time of Van Burens development is really interesting. For example a solid chunk of the south was supposed to be overrun by a jungle from a corrupted GECK. The midwestern Brotherhood of Steel had more in common with Caesars Legion, and also recruited ghouls, super mutants, and sapient deathclaws. And just look at the New Vegas DLC for an idea of what the plans were for in the southwest, most of the DLCs are based on different areas in the Van Buren design Docs.
