I disagree, you are probably one of the unlucky few that is also very vocal about it. There have been plenty of "I love this game" threads too. I'm sorry that you are having bad bugs, but I don't think you are in the majority.
Think again, people facing bugs and crashes ARE the majority of New Vegas owners. All of my friends at work and from school all face the same gamut of bugs and crashes that I do; and I'm not just talking about three or four of us but actually 14 of my friends and co-workers that have the game and experience these problems. Just looking around my small community I can surmise that this problem is definitely on a large scale.
P.S. Don't get me wrong, when the game is running good, it has no equal for me. I love this game but the crashes are bringing me down.
