Excellent game - mostly.
This "Ultimate Edition" includes all DLC (4 added-on chapters, and various added-on weapons & gear) on one disc.
However it comes with no documentation - no manual, no booklet, nada.
This made for some early frustration (being new to the Fallout series) before discovering things like ALT to aim (aiming is fairly important) - or holding R awhile to lower your weapon (less important).
The role-playing aspects are not as intricate or sophisticated as Oblivion or Skyrim; it's more of a "shooter" than those games.
That said, the computer-hacking mini-game is fun; as is the in-game gambling - both in casinos and through an invented game ("Caravan") that's quite good (if initially poorly explained).
One caveat: the first add-on ("Dead Money") is possibly the Worst Game Ever - but (as with 2 of the better 3 add-ons), once begun, you have to finish it to get back to the main game... which I found miserable drudgery.
I'd have liked a manual (found one online); and in another play-through would just skip the one horrible chapter... but OVERALL, it offers a lot of fun.
