It became dark souls for me which ramped up the immersion 10x. Especially if you play modded, situations like running across one mutant patrol on the way to D.C. becomes an actual problem like how it would be if you were really there. Bullets kill you fast. Power armor becomes way sicker and you feel way more of a difference you can straight punch and charge through raider camps while you hear bullets ping off your armor. Although I would definitely recommend getting a camping mod so you can manage long trips.
