That is incredibly disappointing. In a lot of ways I like New Vegas better than F3, and to give it a final ending seems to throw away the experience of being a waste explorer. It's like, I affect a huge change on this civilization but I don't get to see the changes in action except in a sub-par slideshow. Fail.
Also, many of Obsidian's staffers developed Fallout 2, which was also open ended. Don't get why they would toss out that formula.
Multiple endings, do you know how many time one need to create amounts of GB for that???
A DLC is not enought for that,
Fail?
I dont think so,
Fallout 2 was an easter egg after the ending, and the effects are the same, nothing changes, it all the same, Arroyo is still destroyed
Now, if you have a better Idea, I can listen, but if not, then dont say that was bad idea,
