i agree wish fallout 4 was like that. hate this new direction
Bethesda would never do this since they love pushing out new content. However, they could give permission to another company to do this like they did with Obsidian for New Vegas. Although with the way Fallout 1 and 2 are set up, the only ways that would work is Wasteland 2's style or have 1st person view for the main areas and an updated travel map for fast travel. Using Fallout 4's tech on Fallout 1 and 2 just wouldn't work due to how much area that would need to be rendered.
