For example: I would have greatly preferred getting a DLC with the Burned Man as a companion like Arcade of Veronica in the primary game world and -nothing- else. No new weapons, no new area, no more horrifying cazadores trying to kill me, just one scary companion with a grudge and a lot of dialogue and story to unlock. Was I the only one who, upon speaking to the Burned Man, wanted to drag him back to Mojave and help him kill Caesar? Get more of his thoughts on the NCR? Hear reactions from the Legion upon seeing the legendary Burned Man*? Take him to get ice cream?
Or, if just one companion isn't enough to sell a DLC, why not use a DLC to fix a weakness in the main game? The Legion is criminally underdeveloped, why not use a DLC to unlock a Legion city you can visit and quest in? Or, alternatively, wipe out and have some lulz about it with Chief Hanlon and the Burned Man later over a beer.
My point is, why not try to integrate the DLC into the game so that it feels connected, and not like a completely different game?
*I suspect it would be a lot of screaming and pants wetting. Well, they don't wear pants, but you know what I mean.
