I arrived late at the FO4 party.
Let me tell you this, I played Fallout 2 10+ times.
Never been able to finish it because every single time I took SO MUCH time that when I arrived at the end of the game I lost interest.
I somehow finished FO3.
I couldn't finish FO-NV for the same reason, despite playing it multiple times.
I played FO4 so fucking much that I'm at the end of the final mission but I can't find the interest to go finish it.
Doing infinite number of repetitive quests took its toll. I finally got bored of exploring before I could finish the game.
Other than the unending repetitive quests, it was the best game ever for a Fallout fanatic like me.
