What kind of problem? The first playtest review like, 2 years ago almost, said that the crowds felt impressive? The videos don't look like its a problem. The only thing is that they only have one quippy voiceline, but come on, you can't expect more...
A review also mentioned how the NPCs start freaking out if you stay near them too long. Like, get afraid of you or start picking a fight? Seems fine to me.
Yep if you stare at an NPC too long they will start giving you weird looks in return like. ' wtf are you staring at? ' I'd also imagine some even pulling a gun on you but that's not confirmed
Also the NPCs that might 'look' similar can be different with the randomized cyberware they have so you rarely see two identical NPCs and honestly it's not a big issue as GTA had that shit for the longest of time and I barely pay attention to that.
I only heard that some of the crowd density was " neerfed " but it was still by some accounts the most detailed and ' lived in ' world with many buildings with unique interiors and textures so you wont be seeing the same wallpaper or prick ground that you already saw a few blocks onwards.
Let's not even mention that there is the upper and below section of the city which we haven't even seen much yet.
