I loved Fo3 It is still one of my favorite games up there with Bioshock and Assassins Creed 2, but i could not get into fallout NV at all
i rented it out for a week but only got to level 3 before putting it down and not playing it again should i give it another go?

What did you find so difficult about it?

Apart from the 1000's of bugs it's not that's bad of a game.
