I'm not a fan of the first hour, I hung a fallout 3 and it has compared the new vegas is more complete. Graphically it is similar NPCs resembles those of 3. But the content is more detailed eg raiders are replaced by several gang and ammunition there standard, the hollow head, pierce the shield, for it karma general it is no longer just concerned communities (yes if you made the wrong one has not prevented her from being seen by another) to win PV eating food must be a period waiting for her to make effet.Il also has more weapons, more subject for care.
So if you love Fallout 3 you'll love the new vegas
