Mmmm.... It seems to adopt bad parts of RPG with perks and attributes mostly about boosting numbers (e.g. increase damage of pistols, higher chances of critical hits etc.)
Would be great if most perks and attributes are geared towards unlocking new useful abilities. Like in the Deep Dive, it showed how high Body attribute allows us to melee an enemy in mid-combat and turn him into a human shield.
Or maybe higher Intelligence attribute and perks allows V to hack more sophisticated technology. (e.g. V cannot hack enemy cyberware with low Intelligence, but can still hack Vending Machines to distract enemies).
Just think Deus Ex Mankind Divided. Leveling up is not all about the numbers.
How does RAM work in Cyberpunk 2077?
Your maximum RAM will increase based on your intelligence attribute, so if the hacks you want to use seem a bit expensive, there is a 1:1 correlation between maximum RAM and your intelligence. You may also find cybernetics or equipment at the Ripperdoc that increases this number as well.20.12.2020 г.
Quick google...Anyway if that is right, then the problem is not as stated above, but that some cyberwar needs higher stats than it currently have. I mean you relatively quickly get enough credits to install some nice cyberdecks with lots of ram. What you are asking for (more advanced machines being harder to hack) is already in the game, it's just that the nice cyberware that give you a lot of ram is easy to access
Btw I think body attribute still effects how long you can hold someone before they escape.
Edit: Tho to be fair - maybe how hard it is to hack something, depends on the area level compared to my own....
