I finished Deus Ex Human Revolution and Mankind Divided recently, and oh boy it beats Cyberpunk in every aspect.
Regarding loot mechanics - in deus ex the loot is static. A pistol is a pistol, there are no levels of loot. Pistol headshots always oneshot kill unarmed enemies without helmet. There is no beating numbers out of enemies in the game. And with armor piercing upgrade pistol can headshot kill armored enemies. And imagine, I didn't get bored of carrying the same pistol through the 60 hours of playing both deus ex games, it felt just PERFECT
Leveled loot system is POINTLESS. It doesn't introduce interesting gameplay tasks, it adds nothing except an obligatory activity loop that distracts a player from main gameplay. It doesn't test my reflexes, it doesn't test my intelligence, it doesn't test my strategical, tactical and quick thinking, it doesn't test my patience, we have stealth for that. And it doesn't provide customization options, because they look the same. This is a boring routine, and I hate it with all hate I have, because I waste enough time on routines in real life.
Cyberpunk loot system just wastes my time and gives me nothing back.
