Can't even read a word you said, learn to English.
Learn to English? Now, that isn't proper use of the English language is it mate? :rofl:
Tough question really. Depends on what you are looking for when you play one. If you are in the mood for a good story and lots of walking around without much to do other than mod your guns, then NV is definitely the game for you. (Not bashing the game, this is true. Once you kill something, that area is pretty much empty. I'm doing a no fast travel playthrough at the moment and walked from Crimson caravan to Mojave outpost. I got to kill one ant on the journey.)
If however you don't mind a bit of a cheesy story but want to explore and get into lots of gunfights with random encounters, it's gotta be FO3.
