Although I technically did like 95% of the things in this game, some people at this point would just dump their copy of the game on a shelf and let it gather dust, but my liking of Fallout is so great that I will gladly start to replay everytime a new dlc comes out. But then after having finished, I will fall back into boredom (maybe I should redo that gambling character of mine with 10 luck...)
I therefore think that its not the game that is lacking, but perhaps the content is not sufficient? Although this isn't really true, as I'm pretty sure I overplayed this game.
Sorry for the randomness of this topic, I just felt like I wanted to show how much Fallout is great
