This remake itself is a lot like a cyborg; A 30-year old decomposing carcass of gameplay design fitted with enhancements for the modern day. Sure it's fast and looks good, but once you get close enough you notice the smell.

As a FPS, it's below average; Weapons have barely any feedback outside of muzzle flashes blinding the player, the AI is just as dumb as in the original and the game has a mechanic where it will not allow you to shoot/hit if you're too close to anything (Enemies, walls..). This forces a lot of play with positioning while enemies can hit you even when you can't see them, because the player hurtbox is extremely wide for whatever reason.
You'll probably also get the occasional salty death from explosions traveling through walls.
Leaning is tricky to use since enemies hit you anyway and your shots come from the weapon model, so very fine adjustment is needed to not shoot at walls. So much for fancy targeting implants that do not even adjust the crosshair.

There's very little the game actually does for you; The map has a slight visual upgrade while level design and progression overall are just as confusing and labyrinthine as in the original.
Remember that audio log that you found two hours ago, that explains what you need to do three hours from now? The remake certainly is faithful to the original in the sense of not caring at all if the player makes progress or not. Suspend your disbelief as you write down passcodes on a piece of paper (Hell, take screenshots if you're really hip).
Despite having played the original multiple times, I still found myself shaking my head in frustration and cursing under my breath, trying to figure out where to go as I had lost direction being immersed in the world.

This can be a great strength of game design of course; Creating a world that exists in and of itself, instead of just serving the player. It's also a balancing act that the original game failed, and the remake chose to ignore.
Maybe adjusting story difficulty does amend this slighty, like in the original, but there's no way to do this mid-game.
The insulting Quality-of-life feature this game did choose to implement (After effectively reducing the inventory size from the original) was to add a "Cargo lift" system that acts as an item box throughout different levels. But this is too small, and you'll most likely end up having to throw items on the ground (Which thankfully never disappear) and remember where they are.
Outside of that, you can take on the role of a janitor bot, "vaporizing" various junk found along the corridors and rooms into scrap, which can then be recycled for money to buy ammo, upgrades and consumables.

The visuals are where this game is at it's best; Lighting and fog effects accentuate the carefully recreated levels of the original. Moments of distress as a laser beam flashes, exposing the security cyborg taking aim at you, or the slight glimpse of movement in the dark from a cyborg assassin that is nearly invisible.
Every nook and cranny is crafted with detail, the textures pixelated to create a "Retro HD" look.

Sadly most of the audio doesn't hold up; Gone are the cold, metallic and loud SFX of various interactions. The Magnum that used to sound like a cannon is now a broken synthesizer. Nothing is memorable or stands out.
Music has the same problem; What were once quirky and oddly upbeat electronic tunes have been remade into something that just blends into the background, atleast until the overbearing distorted guitar takes over in combat. Combat music that seems to kick in 10 seconds too late, and stay around for another 20 after the last enemy is felled.
With that said, atleast voice acting stands out well enough, in audio logs as well as Terri Brosius returning to voice SHODAN, with the approriate post-processing giving her lines the feeling of dread and unease, commanding presence as she speaks.

Cyberspace sections are vastly improved; They retain the same general idea as the original, while being actually being controllable and navigable.

In the end I'm left to wonder, who is this for?
- For the younger generation you present an extremely bland, confusing and frustrating first-person shooter that is way too concerned with being an "authentic" System Shock.
Of course, it still retains lot of the strengths that left such an impression on me when I played the original ages ago; Presentation, world-building and exploration.
But it drags all of the baggage along with it.

- For the older players and people who love the original; Are all of the changes and omissions really worth it just so that you don't have to use keyboard to turn?

The developers also struggled with how this game should be remade. Following the initial Kickstarter campaign all the way back in late 2017, it was later announced that the team had to go back to square one, since the "first" remake had become way too different from the original game.
Several years later, we now have the almost 1:1 remake on hand.

If you're curious about video game history, atleast try to play the original before trying this.
