Definately one of the better games to be released in about the last 5 years. A vast improvement on Fallout 3.
There is so much content in the game, there is no reason why you wont get over 100 plus hours out of this if you go round doing all the optional quests.
This version includes all 4 addons which are great fun, I particularly liked Old World Blues, it was not what I expected at all and was cleverly written.
Totally under rated game.
