They should add the Brotherhood as a major faction and give a whole new main Quest line for their takeover of New Vegas and all of Houses tech. I would just like to see DLC that doesn't open new lands like Point Lookout (not saying anything bad about PL) but DLC's that add more locations, and large indoor areas to the map.

Any other ideas? or do you disagree?

I disagree, not just as a House fan boy, but because that directly countermands two particular questlines.

This, As they are hiding because of the NCR and they have few numbers.

That kind of was my whole point a new main quest line to follow! Do you play the quest line every time or are you only playing one playthrough (I don't know how to ask without sounding condescending I don't meen too)?

So....we need to pay to have a main quest that may as well have been in to begin with?

Besides, I've had enough being under appreciated by the BoS courtesy of Fallout 3. Thank you.

While I would probably buy the DLC if they made one and have no qualms with it, I'd prefer if they didn't. I mean, I get the idea and it could be fun, but if I really wanted to play a Fallout game where I run around helping the Brotherhood of Steel, I could play Fallout 3. I know that the DLC would (presumably) be much, much different than Fallout 3, but still, I feel that their efforts would be better spent on some different, fresh DLC/patches than this.

But now I think of it, if they made a massive DLC that added the ability to finish the main quest bringing many of the smaller factions to power (great khans, the Kings, Followers of Appocalypse, etc...) I would definitely enjoy it.
