I now actually feel like I'm playing a Fallout game. It's amazing what a soundtrack (or a bite of nostalgia that actually feels legitimate) can do for your feelings and enjoyment of a game.
Having that playing in the background as I lurked in a dark dilapidated building was an INCREDIBLE feeling. I've been enjoying New Vegas a lot so far, and it wasn't until I reached Primm that I noticed some of the original Fallout music.
