Soooo...
There's a lot of endings in fallout 3 new vegas, but this one had me laughing.
I killed off Ceasar in his brain operation, nuked the bunker, killed the NCR president and killed off Mr. House, created an army of awesome robots (with "Yes man", the smiling robot, as leader) and had the NCR general approach me in the ending of the game - this is how it turned out.
I think this ending requires 100 points in speech.
