I've put 50 hours into the game (Level 39, Very Hard) but I quit before the last mission because I no longer cared about any character.
Let's start with the good parts cause they are very few: Night City, the cars, in-game cutscenes, some quests (maybe less than 5) and the atmosphere at certain moments.
Night City is massive and it looks really impressive. It's the single most important highlight of the game. Each location has an insane amount of details. The same with the cars.
Other than that every other aspect of this game is sub-par or mediocre at best: ui, movement, combat, driving, stealth, AI, exploration, itemization, crafting, skills, level-scaling, quest-design, writting and story are garbage-tier.
UI is designed for consoles but I cannot phantom someone which likes to press a button 20 times to dissemble 20 weapons each 10 minutes or to manually scroll through dozens of shards.
Movement is clunky which is simply unacceptable after "8 years" of development. If you cannot implement proper fluid movement then you have no business with fps games.
There is something fundamentally wrong with the character's animations outside of in-game cut-scenes. These issue are very noticeable when you sneak on stairs.
Combat is a mess. It's very hard to aim when everyone is moving in bizarre ways. I gave up on this shit and I went for smart weapons.
Driving is competent. I actually enjoyed it but at the same time the cars feel very floaty for some reason.
Stealth is retarded. I got the implant "slow time on detection" and I could basically run while crouched all over the places. Also there are only two animations for stealthy taking down enemies.
AI is non-existent, in combat or otherwise. While racing the AI cheats by teleporting behind you. I suspect the enemies don't have any AI for driving and everything is scripted (probably manually).
Exploration is garbage because most locations are generic and a couple of them are even reused. Also the game overwhelms the player with quests soon after the world opens up.
Itemization is bad. Each 5 minutes you get a weapon which is better than what you have. That's why I specialized in crafting asap and I could use the same legendary weapons for the last 5 levels.
Crafting is as simple as it can be but the upgrade system is bullshit because the required resources increase dramatically after 1 or 2 upgrades.
Most perks are useless while others are must-have. I specialized in critical damage with rifles and my sniper was doing 100k+ damage per shot because stacking multiple x% is a sign of decline or retarded game designer. Funny thing: Sasquatch went done in one hit from my sniper rifle. I reloaded and I left her live.
There is a secret leveling up based on your main level. You get to a location and you cannot do shit because your weapon is doing 1% damage pet hit. You fuck around in the world, you gain 5 levels, but you don't upgrade any combat skills and suddenly you are doing 20% damage per hit.
Level-scaling is the same imbecilic system from TW3.
Quest-design is a let down. It's true that there are not many fedex quests but at the same time most quests are just pointless kill/steal quests.
The writing is simply not mature enough for a cyberpunk game. The game feels like it was written by edgy teenagers without any real life experience.
Story is mediocre at best. Somebody had a hard on for subverting your expectation pointless betrayal and revenge tropes. Also strong independent women.
That's about it. The game is fucked because its design is fucked. There is no way CDPR will be able to fix this mess.
It's more like a 4/10 or 20 potatoes game. Nice for sight seeing but that's about it. I had more fun with Fallout 4 than this crap.
