This is a Bethesda game through and through, so if you loved their previous outings, than this is the kind of game you can fall in love with.
Is this a perfect game? no, there are still bugs here and there, and some design choices would have been cooler if they had gone in a different direction, but at the end of the day, it's one of those games I can start and several hours will pass without me realizing.
At this point in time I've clocked 40+hours due to early access, and I've barely touched the main story missions.
For me, this is definitely a game I will still be playing for years.
