Gathering Delamain’s children (Human Nature, Tune Up, Epistrophy, Don’t Lose Your Mind)

Cyberpunk 2077 has a few types of collectathon quests, but the Delamain cabs ones are probably the best. The questline starts with a simple call from Delamain, the AI that runs a self-driving cab service in Night City, as several of his cars have gone MIA around the city. Each AI-powered car you round up has a distinct personality. Some are great, like a car terrified of drive too fast that you have to carefully direct back to its home base. Some are obnoxious, like one that is literally just GLaDOS from Portal, which was a dated reference in 2020 and even more dated now. But it all culminates in a final quest that gets into some light immersive sim elements and has a pretty great decision to make at the very end.
