So, I'm here again.
Now, I got a review about this, so I'm putting this out here now. I will be doing the DLC in order, meaning it'll go Dead Money, Honest Hearts, Old World Blues, and Lonesome Road. Mojave companions will stay in the Mojave. If you can't take em' in game, not takin 'em here.
Second, I do have something beyond Goodsprings. I'm currently finishing up Primm (My Kind of Town, for reference), and will be moving on to Nipton, and finally Novac after a brief stop at the Mojave Outpost, a certain ranch, and finding a certain wreck. Plus an irradiated hellhole. I completely forgot how tedious the first part of the game is, but once Novac is done, things start speeding up a little.
Finally, companions. They have quests. Here's how it'll go. The Courier will have two companions, plus either Rex or ED-E. It's this way so companion-companion dialogue is a thing (And why did Dogmeat not get his own companion slot in Fallout 4? Off topic), since in New Vegas, you're only allowed one human and one not-human (Meaning Rex/ED-E).
Just clearing things up on those fronts.
