Bethesda has clearly stated that New Vegas is not an official sequel to Fallout 3, but should be viewed more as a spin-off.
Sho, forgot this was made by the same people that made Alpha Protocol. That game really made me lol...it was 3D and yet the character seemed to only move at 90 degree angles to the world. What a waste of an amazing concept. Pah, lets hope someone else picks up the Spy/RPG idea.
Anyway, I can't wait for my poker chips and deck of cards >:3
