This is as close as one could possibly reach to playing Fallout 3/New Vegas in the Fallout 4 engine until such a time that the Fallout 4 Capital Wasteland and Fallout 4 New Vegas teams are able to release their full recreations of those games. Everything from equipment to gameplay and visuals (including custom ENB presets for both profiles) has been overhauled to match the feel and aesthetics of classic Fallout's.
We have compiled nearly every known and publicly available Fallout 3/New Vegas-inspired mod out there and brought them all together through the use of two profiles that allow you to seamlessly transition between the experiences of Fallout 3 and New Vegas with a couple clicks.
A Tale of Two Commonwealths is an experience based around the concept of transforming the look and feel of Fallout 4 into that of Fallout 3 and New Vegas, respectively.
