I love it since the first day. Got the all inclusive season pass with all the add-ons and spend so many hours enjoying it.
There are certain points in the storyline where your choice alters the course. So even makes sense to play it several times :-)

That is what I liked about all the Fallout series from 1 to Las Vegas. I still play Las Vegas one quite a bit and still have not found all the nooks and crannies in the game.

OH you're so lucky.
I only discovered the series with Fallout 4. Never found the time to look into the former version.
It's similar to my experience with Hive. Awesome thing, around for a few years and never noticed it.
Wish I had been here few years earlier.
