As someone who has earned the Platinum trophy on the PS4 for this game, I can say a few things with certainty.
For starters, the gamma on this game, is awful. There were secrets that I was walking by repeatedly because it was just too dark in the game. I ended up curving it up to 1.3 to correct this issue, and it made the game look pretty damn good. You don't need darkness to make a game scary or intimidating.
The Chromatic Aberration and Motion Blur settings, are useless. Motion Blur makes it more difficult to track enemies while moving, and that's totally unnecessary unless you're a masochist. Chromatic Aberration is just flat out pointless; the game looks and feels better without it.
The rune system is neat, but we never had it before, so it felt out of place, as did the power-ups and weapon mods. While they were GREAT tools for each situation you may face, they were ultimately unnecessary. This isn't to say they weren't done well, because they were, but it didn't feel like Doom to me.
As for the weapons themselves, naturally the Combat Shotgun, Super Shotgun, Chainsaw and the BFG 9000 all felt fantastic. The rest, not so much. I struggled to find a use for the Chaingun outside of leveling the mods, as the Heavy Assault Rifle was just better and more accurate. Then again, if you max out the Super Shotgun, you need no other weapons ever again, for reasons I will let others figure out on their own.
The enemies felt right for the most part. My only real complaint was the Pinkies being incredibly difficult to deal with on the first play through. Those little bastards are downright nasty, and the geometry of the level design was not very conducive to getting the hell out of the way. Pretty sure I died a few times to a Pinky simply because I got stuck on a ramen noodle cup. The Cyberdemon fight was visceral and raw feeling, and I couldn't be happier about it. The Spider Mastermind on the other hand, lacked imagination. Compared to the Cyberdemon and Hell Guardians, he just felt like an anti-climactic end to the game.
The soundtrack was incredible, but the sound effects could be a little harsh on the ears, as they are just over-the-top loud. The prime example of this would be the first transmission you received from Pierce. The static at the end, on the first play, was so loud I ended up jumping out of my chair and ripping my headset off. I have hearing difficulty, and it was still loud.
Overall, the game is a solid, and I mean SOLID, 9/10, at least from a campaign standpoint alone.
