Game was launched as a 1-star game, but has since upgraded itself to 2-stars (maybe even 3 now?).
You effectively have a Fallout 4 clone (same engine, same look, same assets, creatures, and models in most cases), where they added multiplayer to it. That alone isn't a bad thing, in fact I think it's a good thing! The problem is, everything else they did was bad or broken.
Initially they had nearly no story, literally no NPC or living human characters to interact with, and the daily grinding / repeatable activities were extremely boring.
Cheating and exploits are out of control. There is no meaningful multiplayer economy to speak of because cheating is so out of control. People know this old recycled game engine in and out at this point so exploiting it is extremely easy... not to mention the developers are a small off-shoot studio with very limited resources and no real motivation to fix these problems as the game population has already mostly vanished.
To summarize, this is not a good single player fallout game. This is not a good multiplayer fallout game (or game in general) and it is not a good "live service" game so what do you get with your time and money? Not much unfortunately.
If you enjoyed Fallout 4 and just want something slightly different but similar... sure, play this for a bit. If you've never played Fallout 4, then play that, it's the same game more or less and much better.
