I liked fallout 3, easily my favorite bethesda game but not enough to finish it.Fallout NV is almost as good. It has great exploration and I played all the dlc. I put close to 200 hours in that game. If you like fallout 3, you like new vegas
I played new vegas for about 30 minutes before shelving it. The location wasnt nearly as interesting as the wasteland and in those 30 minutes the game glitched out twice.
I feel confident enough to say that feeling when you first walked out of the vault snd saw the wasteland in 3>>>>>>> anything in new vegas
