Never played the game, had no backstory to go by.
Have watched ep 1-3 so far. It is ok but currently moving a little too slow for me with too much time wandering through the wastland. Lots of questions I rather they be answering but I'm sure they will get there, with only 8 episodes they need to start getting there soon.
I feel like there are a lot of crossover themes with another show I liked, "Silo", as far as the vault dwellers and what is/was going on there.
Overall I'm still hooked and plan on finishing this week.
