Watched the whole thing.
If they can pull off 3/4 of what they were showing, it will be a pretty good game.
If they pull of 100% of what they showing.....
Here's the thing though: this all reeks of scripted gameplay. The mission is probably legit. But a lot of what else I saw was clearly scripted. The voice overs use the demo characters name, for example. (Maybe that's just the default character or something.) The scav investigating the car. The attack by scavs while driving the car. The hacking system clearly looked like a mockup meant to dazzle, because there was so much shit there they just "noped" right past.
All that said, I'm excited if they deliver on some of this. Especially the combat mechanics. Bullet time comes as no surprise (even though they try to make it badass like it's not a, what, coming up on 20 year old gameplay mechanic?), but other things did. Wall running. Super man leaping. Possible? super strength. Smart guns that just shoot at visible targets. Drones. Hacking enemy networks via enemies to disable them and all sorts of other shit. Weapons penetrating cover. Terrain destruction. Data views and combat overlays. The list just goes on and on.....
Outside of combat there's a lot of promising elements too. Scanning the environment Arkham Asylum style for clues and useful information. Investigating items in your inventory to reveal all sorts of info that will likely be story and mission relevant. Skills like Hacking or Engineering and who knows what else. Driving and whatever comes out of that.
In other words I'm excited but I'm realistic. If something seems too good to be true, it probably is. We've all played enough 1st/3rd person RPGs to know how promising ideas can become bland and boring in implementation. (*cough* Fallout *cough*) I've played all the Witcher games and I feel like I have a good sense of what those mechanics boiled down to. How random events and game systems have fallen flat in the past in CDProjekt Red games. I guess what I'm saying is if Cyberpunk 2077 lives up to what it just showed us, it'd be an order of magnitude more detailed, deep and well executed game than anything else I've played of their's. The Witcher 3 is good, don't get me wrong, but I'm not sure I'd call it the Best RPG Ever Made as some have. If Cyberpunk 2077 really dials in all these systems they've shown instead of making them one-note flourishes to gameplay, again, it'd be better than everything else I've played by CDPR. Particularly the UI work. Holy shit, a lot of the in-game UI is stylized and visualized as part of the world. Menus, notifications, doing stuff and things. Compare that to Witcher 3's flat, boring, practical, easy UI screens. Just looking at the implied UI work in CP2077 is making me go "Uh...the whole game is going to look like that? Really? TFW you don't know whether to drool with happiness or call bullshit."
So I cautiously await the Hype Prophets and pre-release reviews, and I hope they're critically minded. The sky is pretty much the limit when it comes to expectations of a Cyberpunk game, what's possible, how dynamic it should be, and all that. And I'd really want some reviews to pay close attention to these systems and tell me if they delivered on the hype, or just sold us a glossy, neon-finished vision of the future.
