I do understand the game's criticism, and after 2 years of patches and expansions there are still parts of it I don't entirely like.
And I know how casual it is compared to some other games of similar genres ...
And yet, I cannot put it down. I just love it. Playing it feels like it was made specifically for me.
Hardcore Fallout fans hate this game and ol' Todd due to it not exactly carrying out the elements New Vegas and 3 had, but again, Fallout 3 and New Vegas looked visually dull and all the NPCs looked like ass. I think Fallout 4 has a greater immersion and keeps me more entertained. I love the new elements it bought despite ditching some old ones, and I love the characters as well, they feel more like a person than Microsoft SAM.
Alot of people seemed to be rather dissapointed with this one, largely because of it's harry potter styled cliff hanger ending. Plus people really blew the whole micro transactions thing out of proportion. Other wise it's a solid game that improved on what the HR did good, like the augmentations, the story and introduces more intense issues. However it oddly did away with some of the things that made Human revolution challenging. The boss fights. Other than that the game looks great, almost like a love child of half life 2 and HR, and the models and voice acting are great. Also the new augmentations are heaps of fun to use on both lethal and non lethal runs. Think it got far more shit than it deserved.
