- performance is better than ever
- graphics are out of this world, truly next-gen stuff
- new perk system completely changes how you play the game
- loot is completely changed, a lot of nonsense removed
- healing items and grenades are infinite but on a cooldown now, you have to be more tactical
- cyberware mechanics completely revamped, makes so much more sense now, even has a tiered system
- clothes are just clothes, no more armor stats. Again, makes so much more sense
- a lot of missions received QOL improvements to make them more immersive (Wakako doesn't just give you the Tyger Claw tattoo cyberware, you have to go to a ripperdoc; Padre doesn't introduce himself as if you didn't just do 6 months of missions for him anymore, etc.)
- level scaling means you don't run into enemies that are 20 levels higher than you, it's a level playing field
- NPC AI is better but still not great
- Enemy AI is much better, more realistic
- UI is completely reworked, especially noticeable in the journal/quest log, and the phone menu. Works much better now, more intuitive
- NCPD cops are actually patrolling the streets, both on foot and in vehicles
- Johnny Silverhand seems reworked, looks even more like Keanu now
- Still no NCART system though, unfortunately. Was never promised but it would've been baller to use the metro and take in the sights
It's a huge list of improvements.
