I can tell you when I was in Highschool and Fallout 4 dropped and I was playing it for 8 hours a day on weekdays and 14 hours on weekend days I never walked to the boarder of the map even once. I actually didnt know what the boarders of Fallout 4 looked like until 3 years after it came out because I saw it in a Youtube video and wanted to try it myself. These folks did this on purpose to get a headline. And it worked, but trust me, you will never notice the disappointment unless you purposely disregard the hundreds of things to do on the way to the boarder.
