Not "dialog" per say, I'm talking about here. It doesn't need to be anything but short oneliners that might offer:
- Info about (and trigger to) a close by random encounter
- Info about a job the player might have in his to-do list
- Random trivia about Night City and its goings ons that might or might not be useful
- A "Fuck off" or "I don't have the time right now" response (which might be the most usual thing you'll ever hear, but when it isn't, it's rewarding)
That kind of stuff. Just little things, in addition to the other forms of small interactions (pickpocket, pick a fight, seduce... what ever might fit the bill). The NPC's that are meant to have dialog, have it already.
This is essentially what Red Dead Redemption 2 has done with its dialogue system. You can greet, antagonize, threaten, or rob literally any NPC in the game. And you never know how the interaction will go.
I was riding through the countryside at night and came across a camp with a lone individual sitting at it. Most of the other campers I'd come across just tell me to fuck off, and if I don't, they pull a gun and threaten me until I do.
This guy, however, invited me to come sit down and take a load off, which I did (used his fire to cook a bunch of meat). After talking for a while (he'd say something, then I can respond), he got bored of my company and told me (politely) that it was time I was on my way. I was still busy cooking so I ignored him at first, and after several more warnings (increasing in intensity) he pulled a gun and that got me out of there real quick.
Of course, these interactions will eventually wear out (you can only record so many unique lines of dialogue, and if you talk to almost everyone like I do, well...), but it was admirable of R* to try.
As much as it sounds like I'm just tooting the game's horn, there's a point to all of this: random NPC interactivity can be done. It's the one thing we never thought would be possible, but it is, apparently. And it's BS to say it can't be done in a game like 2077 just because it's more complex, because RDR2 is ridiculously complex and it works just fine.
I liked your images. Simple, but I believe they would be effective. Maybe if you seduce someone successfully, you can take them back to your apartment and bed them, with just a few lines of dialogue during the trip (no deep character development needed there - interactivity is the goal here, not story).
Maybe threatening people can act as a robbery, a la RDR2. They will respond differently depending on who they are.
