This is the kind of game that appeals only to RPG fans because the quests are not the fedex quests, there are multiple choice, implications, a searched decor and such a vast universe with its atmosphere, its details, its discoveries ...
The last time I stayed glued to a game like this was Morrowind ...
Sure it is less beautiful than Skyrim but the quests and the world are less polissés, besides that one is in the presence of an old RPG with points assigned in a particular characteristics.
Skyrim was for him the most beautiful animations, a more evolved combat system of landscape design (different desert far in this game).
Say FONV makes you want to search everywhere, and it becomes cash to fall by chance on a place a weapon or a subtlety that we had not seen in the previous part, and that it is priceless.
In short the current price, and with a few mods this game is well worth the blow to buy it.
