The story of New Vegas was a way better than FO3. I understand the concept of revenge but i had some problems with the " i seach my daddy in wastelands, because i miss him so much, even though he has abandoned me in a bunker to let my die there." thing.
Not to mention the end of FO3. (I had a supermutant with me, who could survive the radiation, but he dont wanted to do it. Haa, it is your fate my ass.)
