A DLC is essentially an expansion of an existing game. There are direct ties to the environment of the original game. As an example, for Fallout 3, you have Operation Anchorage, The Pitt, Broken Steel, and Point Lookout. A FO3 character can migrate back and forth between those freely, and there is a definite connectivity between the geography of all 5 units (core game and expansions). In comparison, though there is a considerable amount of shared geography between FO and FO2, they are _obviously_ distinctly different games because even though they share the same history up to FO, the fact that FO2 takes place quite a few years later AND you can't carry over the FO character into FO2. Then again, look at Baldur's Gate and BG2: same geography and the same character(s), yet still distinctly different games. That's because BG clearly ended. BG2 is an entirely new adventure that happens to follow a given character (or a new one that is given a backstory to BG). It's sort of like following the adventures of James Bond, Agent 007. Same character in a different adventure, over and over again.
So, yes, FNV shares the same engine, game mechanics, character development procedures, as well as a common history with FO, FO2, and FO3. But given the degree of separation, it is very clearly a stand alone game.
