Fallout: New Vegas is so good it'll make your head spin, quite literally in the case of Doc Mitchell.
The first character you meet in New Vegas can't control his head, which spins around while he talks, before he floats around the room while his bonce flops down to chest level.
While that would make for an amazing opening, it's definitely not how the game's intro is supposed to play out - check our walkthrough of the first 20 minutes of New Vegas to see how it's supposed to be.
