First you have to check to make sure that you can transfer the files. Some game files are protected. If they are not protected then you can simply just put the save data onto a USB and transfer it that way. Hope this helps!!
Occasionally Fallout: New Vegas will freeze, but not as frequently as Fallout 3.
They most likely will, though Obsidian is making Fallout: New Vegas (which is not Fallout 4, it's just another game in the Fallout world)
fallout: new vegas 2 I've heard.
Fallout New Vegas is the fifth installment in the Fallout series. It is for the Xbox 360, PS3, and the PC.
As far as other people know. Probably. Because they have so many people who like Fallout New Vegas, that if they make another one; everyone would want it. Hope that will get you exited! :)
In my opinion, Fallout 2.
Fallout new Vegas
No, you can't get married in Fallout: New vegas, but you can have sex in the game :)
Fallout: New Vegas
fallout new Vegas will be on PlayStation 3 and Xbox 360
Yes, called Fallout New Vegas. It's 3 or 7 years after Fallout 3. There will also be the NCR which are the new republic of California (which are from the previous fallout games). Go to ign and check it out or fallout wiki.
Nothing in New Vegas spoils Fallout 3. They take place in 2 completely different corners of the country. And New Vegas can not spoil anything for Fallout 3, as New Vegas takes place before the events of Fallout 3. Hope this helps! Also Fallout 3 is not a sequal. But lets pray for a Fallout 4
