I think the biggest asshole in CP2077 is the way that cyberware stats work.
>You can't re-roll them.
>They're always a combination of three random stats from a list of like 30 potential stats.
>The values of the three random stats are, themselves, random.
>If you want to buy a new cyberware augment and get three more random stats which are themselves random in scale, you also have to upgrade it again.
>Upgrade materials are scarce.
>The cost to rebuy cyberware is steep.
Why does this system even exist? It's completely untenable to re-roll and re-buy and re-upgrade so that you might PERHAPS MAYBE stack even a single cyberware stat across your cyberware; even to stack one, the way the system currently works you would need thousands of upgrade materials and millions of €$; the mechanic is unsuable without cheats and mods.
The system that they implemented for CW stats is patently unfinished because it's nonsensical and doesn't work, the system shouldn't have left the alpha state the way it is, let alone right here five whopping years post-launch at version 2.3
But that's just me!
