The death of Adam Adamowviz was a huge blow to the art direction to Fallout 4 which originally was going to keep the design language of F3 and FNV, but decided to go in the most Jetsons Route because of reasons. I honestly prefer the older designs of retro futuristic underpinnings rather than this wacky bullshit.
I know people will point out the wacky stuff in F2 and say it's never been a serious franchise but it's also a game where along with becoming a porn star, you can become a child killer, a slaver, and that if you play a lower int female Myron attempts to drug and possibly rape you.
Hell with the restoration of the lines of the Fiends leaders someone like Cook Cook is so depraved and insane that people like him should be living in the Shivering Isles along with the wacky bullshit.
