Why not make video naming everything that Cyberpunk has and GTA doesn't ? hundreds of features. Quite literaly.
Name 20
Let me start in contrast...
NPC no matter what kind can be pulled into some sort of dialog
NPC´s actally reacting to threads
The option to step into a cap in the middle of nowhere and the AI will still be able to navigate you to your destination
collision avoidance
Police that actually chases you beyond two blocks aka Police not just spawning in behind you in an alley
variety of Hookers
Online Gameplay that holds up for years
The ability to change the look style of your vehicle
The ability to change your hairstyle
The ability to buy additional clothes / also exists in CP
The ability to redo missions
Multiple flying vehicles
questlines that guide you how to use such vehicles / flight training for example
boats / races
a variety off different races
Monster trucks
a pretty damn well thought out stroyline / epic characters such as trevor
a UI that works and wont let you stop and turn back everytime your speeding
several locations that look different from another
a weather system
not perfect but well made physx
mutiple characters to control
Heists
enough side stuff to do or just to explore
i could go on but im eager to hear about the 100 things CP has that GTA does not
you already named hacking, you cant name stealth since there is an element of stealth in GTA aswell if you want to play like that also there is blunt weapons and swords.
GTA has mutiple endings...
So that leaves you with augmentation - 99 to go the stage is yours
But as mentioned above this game never was made to do all of that, and as long as you are in the main story or on a sidequest it does its job pretty well.
Its just a shame that it doesnt have these things, otherwise it would be to good to believe.
