The return of the companion system is great specially making their related quests.
Better developed environment compared to FO3.
The Karma and reputation being separated makes the player decisions more simple when facing relationship and moral issues.
Hardcore mode for the win.
Weapons, lots and lots of them.
Consistent fluff with previous FO games, unlike FO3 (eg. NCR expansionism and BoS being the dicks they always were).
Combat armor is awesome once again.
This game served as a small excuse for the work of modern developers and their products. Many of us know that in the present time the majority of games are made and sold with the use of standard business model.
FNV was a really nice dive into the old retro-scifi atmosphere of classic Fallout series. The return to orange gamma after FO3 (which does not fit to Fallout IMO), old Fallout OSTs by Mark Morgan, new vaults with horrible and nevertheless exciting settings, dialog options with similar variety of humor in some cases...
However, as we sometimes say in Russia, if you want to make good for a person, make bad things to him/her instead, and then return the things in the previous state.
When you proceed to the very end, the game tends to be more and more like a post-apocalyptic FPS. The turn-based mode (named VATS here) is suitable and convenient only for fighting with Deathclaws. I even did not manage to complete the game, because I figured out that my biggest interest was in completing side quests, not finishing the main storyline.
The four addons coming in Special Edition can give some more hours of gameplay, but they don't save the game either.
And when I completed them all, and discovered all the locations on the map, I even was not able to start the game from the beginning again, because everything is learned by heart.
Still, I think that this direction for the modern Fallouts is more suitable than this of the Fallout 3.
Too bad we will not ever see Van Buren.
