The more I play this, the more I think it should have just been delayed for another year.
Car damage is nearly non-existent. You can ram several vehicles and your car will still look fine. You can scrape past walls and other cars but there will be no paint damage at all.
Not being able to shoot while driving a car makes car chases entirely reliant on hacking, which becomes very repetitive after a while. It also doesn't help that it seems to be impossible to outrun your pursuers without hacking, no matter how fast your vehicle is and how shitty theirs is.
Some of the sound effects are absolutely atrocious. Every car sounds like a lawnmower and they all have that same damn stupidly annoying horn. And some of the guns sound horrible.
No car/weapon customization at all. You can only change the color of your clothes.
No police patrols or cars anywhere; police will only appear once they get called by a witness and you can't evade the scan, then they disappear when they've lost you.
A witness call is the only way the police will ever show up outside missions; they do not care if you blow up a convoy, destroy public property, cause a massive crash, hit civilians with your car or speed along the highway bumping every car of the road.
Karma system serves no purpose and is inconsistent. You get bad karma for injuring or killing civilians, but not for ramming their cars at full speed or stealing their car.
Once you get the police after you, they will always hunt you down with lethal force.
If you blow up a car in a criminal convoy with a remote explosive, the rest of the convoy will instantly be aware of your location and chase you down.
Enemies will blindly open fire on the last spot they saw you in and just continue doing that until you kill them or sneak around them.
All destructible elements just fall apart in identical bits regardless of the severity and angle of the actual hit.
The 'radio' in the cars isn't really radio but more just a random collection of songs repeating itself.
The constant 'remote profiling' notifications of 'Crime noticed here', 'Fixer job there', etc. is annoying. Why can't I discover things on my own pace and when I want to?
You can't use raised forklifts or garage doors to crush enemies.
You can buy cars in the car app, but some of them can also be unlocked by challenges. The game never tells you this, so you'll have to go through the challenges to find out which ones you don't have to drop money on.
Money isn't that useful actually. You can just steal cars from the street without penalty and faster cars don't help a thing in chases. You could buy some crafting components, but you'll never run out anyway if you just use them only when you need to. You could buy clothes, but they're just different color sets of the standard clothes. It's also so damn easy to get tons of money. You could buy weapons, but the silenced pistol is pretty much all you need.
Random invisible walls.
Stealth missions in which getting noticed gets you a game over. Why? Just let me improvise...
Everybody in Chicago recognizes Aiden as the vigilante, but somehow his identity is a complete mystery to the bad guys and it must be kept a secret.
Dumb AI.
No bullet impact effects on the environment or enemies.
You can just hack your way through some hostile areas without setting foot in them. However, even if you don't get spotted or set foot in the restricted area, if you walk past an enemy after they've become 'suspicious' while outside the hostile area, the enemies will attack you despite having no reason to.
No real-time reflections.
There is a first-person view for driving, but you can't look around while in it, which makes it a pain in the ass.
Car handling is ugghhhhh....
I walked out of a pawn-shop and saw a car crash into the one in front of it. The drivers got out and just.... stood there. That's it. No conversation, no interaction, no argument; they just stood there complaining to themselves. In the middle of the road.
You can sometimes see an Ambulance driving around with sirens on, but it'll just drive around in circles, not going to an actual accident or something. They don't show up when you cause a crash by hacking traffic lights.
And the list goes on.
It's still a solid game and I'm still having fun with it, but this really is not what Ubi promised it would be. I expected something a lot more polished, diverse and detailed.
