I've been playing it since it became available through PS Plus for free in January, and it has been great fun. Frustrating at times, yes, due to being constantly over-encumbered, or dying to Radscorpions multiple times and ending up loosing my Junk, and some bugs, but in general, it surprised me, specially the community.
At some point, players even give away legendary weapons and other stuff to low level players, for nothing in return. And here I was thinking that people would be toxic for no reason in an online experience.
Although, this game, with so many currencies and a lot of monetization going on, it could have been free-to-play from the beggining. Certain features with Fallout 1st would be massive improvements in the quality of life of non-Fallout 1st users. As an example, I could use a Scrapbox, to dump all my junk items into it. It shouldn't be exclusive to the subscription.
