The game itself: it probably will reconcile the fans of the first hour, approaching more in the spirit of Fallout 1 and 2 as 3 without disconcerting the hardcore fans of Fallout 3.
Although well guided in the discovery of the location by the main plot, the player is always free to go about their business freely, except that some areas remain inaccessible for many low-level player, unlike the last title.
I would stick out on history in order to not reveal anything prematurely.
Regarding the collector's edition, here's another gem! You get:
-A Card game each card representing an element of the game
-A Token platinum Lucky 38 Casino
-7 Tokens each representing one of the casinos listed in the game (quality chips!)
-A Making Of DVD of this title
-A Comic book in hardcover cover to read before you start the game (remember to watch the introduction video by the way, but a title of this caliber, I do not understand why the move in the first use
All in a pretty cardboard box.
Finally the game is activated only via Steam, which some are sure to regret it, but something I've learned to appreciate (by dint of scratching my cds / dvd ...)
A must-have!
