I stumbled upon fallout 3 by accident, and it quickly became one of my favorite games of all time. I was extremely excited when i heard New Vegas was coming out and am completely satisfied. as with all video game sequels, New Vegas contains the basic structure of fallout 3 but with updates to everything. at first, the updates seemed way to numerous, the addition of comic books, the modifications to weapons, the addition of several types of ammo for each gun, etc. but all of the updates were fairly easy to understand over time and really added a lot to the game. The game does freeze for a second or 2 put nothing like the glitches i faced in 3. Overall the game is a great sequel to 3 and is an amazing game. i highly recommend this game to anyone who likes 3.
