I think D1 is already a pretty bad game and D2 doubles down on everything bad about it. You can never sneak without constantly duck walking around like an asshole, complete with that fucking vignette, made even more severe than D1's, and you STILL can't toggle it off. You can get seen from guards from the other side of the level, and the light level matters even less than in D1. You have to rely on your superpowers even more because of how badly leaning was nerfed. D1's abstract first person perspective is replaced for pseudo body awareness with immersion breaking animations (most egregious with peeking through keyholes).
The stealth being so much more bullshit is rubbed in your face with a godawful rating system (YOU CAN PLAY IT *YOUR* WAY!!!! :DDDDDDDD). In my playthrough, I attempted to stealth my way through without save-scumming, and I was frequently insulted by the ratings screens giving me an "Assault" rating despite my best efforts to be stealthy. Yet the combat is easier than ever. You even get non-lethal options, so the choice between lethal and non-lethal is even more arbitrary and cosmetic than in D1.
The chaos system, the number one most frequently criticized aspect of D1, doubles down on its worst elements by being based on nothing but your level of lethality, with no regard to your approach otherwise, or, God forbid, specific mission objectives like Granny Rags's poisoning mission. So now the chaos system is even more of a black and white morality system than D1's. It still presents no real C&C. I like how you can kill Sokolov and Billie Lurk (I sure didn't like them), but the fact that you can only do so in the last level cements how pointless it is. Why not let me kill these shitters as soon as possible and pilot the ship myself?
The level design is sprawling with no rhyme or reason, guided by nothing but objective markers. A few levels through the game I stopped bothering to get bone charms and runes altogether, because of the sheer size of the levels and the sheer quantity of collectibles. It's like Donkey Kong 64 or something. It doesn't help that you need the heart to do so, and her dialogue is way worse than in D1. Her pool of lines is extremely small. Most of them consist of either chastising or praising the player for their chaos level, which gets EXTREMELY old if you're going for a high chaos run (contrary to popular belief, D1 really didn't attack the player for going high chaos). The dialogue not about your chaos level isn't even level specific - there's like 5 of them. All of them are just "woe is me, the world is so bad! The rich are so evil! I'm going to swoon!" It's some of the corniest writing I've ever heard - I can't believe a professional writer came up with this drivel. The most obnoxious line that I can remember is the one about the servant who was late with the tea - that one's as tripe as it is overly long.
And this relentless collecting further incentivizes the player to dispatch guards rather than sneak past them - because you're going to be backtracking constantly, and it's easier to take the guards out. So ghosting is a completely senseless and obnoxious challenge in D2. You could only think otherwise if you're accustomed to savescumming.
The story is significantly worse, shoehorning in two playable protagonists and out of place elements from D1's DLC. Didn't I kill this stupid witch already in The Brigmore Witches?
The worse part is how obviously WOKE D2's gotten. Arkane tries to be clever with it to trick stupid people who are still coping about this matter, but it's obvious. Women are now commonplace in the military, despite this not being the case in D1, and the Dishonored setting clearly falling around 200+ years ago. Again, the cope with this is "IT'S A FANTASY SETTING, YOU CAN DO WHATEVER", but D1 presented a world with period-accurate gender roles. It's a retcon to appeal to literally Anita Sarkeesian, who spoke directly with Arkane. Two of these brand new female guards even star in a lesbian romance on a roof in one level. Great. Then there's Emily's mysteriously gender-non specific lover, and the heavily implied gay romance with that one target in the time travel level.
We're somehow supposed to believe Sokolov is a good guy now despite witnessing him commit crimes against humanity in D1. Well, he ends up in a romance with a one armed, one eyed sassy black woman, so I guess that redeems him.
Forgive me if I've mistaken a few details but it's been a couple years since I played D2. It's shit and I won't be doing it again. Like I said, I think D1 is pretty bad and inferior to the games it's inspired by, but it is pretty replayable. I'll replay through D1 once every couple of years if I've got nothing better to do. D2's just garbage. And you couldn't pay me to play that Billie Lurk game.
Still haven't finished Prey. I've got better things to do and, in my free time, better games to play. Couldn't imagine being an Arkanefag.
