Read some reviews on it and even though I enjoyed all the Fallouts, I'm going to pass on this one. It's going to be similar to Elder Scrolls Online which totally sucked.
It's on-line only with no NPC's or storyline. There will be other players running around and it's basically a free-for-all, just like Elder Scrolls on-line.
I personally don't want other players in my game disturbing my gameplay. I don't like "on-line multiplayer only" games, unless they're done right like The Division, where you could play alone or with a friend and not be bothered by anyone else. I was hoping for another "real" Fallout game, but instead we're getting this crap. I think most Fallout players would were expecting another single-player "adventure" experience.
This game just seems like a money making ploy by Bethesda.
