I'm not sure exactly how long it took me to beat it, but I put well over 100 hours into Fallout New Vegas (including several restarts to try different stat combinations). That also counts as the most hours I've put into any game ever of any genre. I didn't mind the length, though, cause that game is really more about the journey than the destination so by the time you finish it, you've had an epic, unforgettable experience. The best part is I was playing the standard, vanilla edition so at some point, I can pick up the rerelease that has all the dlc and play it again.
I'm not a glitch, I just have pixlexia.
