Also, they need to retune some of karma effects. I got in more trouble with the Legion for raiding a tiny slave camp and freeing a couple of powder gangers than for betraying Caesar and helping Mr. House and the NCR to undo everything he's spent the last four years setting up. The first one meant ASSASSINS, ASSASSINS EVERYWHERE. The second one meant... nothing happened. Though admittedly I got so into the story that I just beelined for the ending so perhaps I didn't give them enough time to show?
