What would make a GTA VI robbery feel unpredictable?
For me, it would be enough if robbing a store is not always walk in, point a gun, grab a few bills, and run out with the same two stars.
A gas station at 3 a.m. could be a small score, while rush hour means a fuller till, more people watching, and a better chance that someone gets involved. Leaving your car out front could make the escape worse. Stuff like that. Every robbery does not need ten stages; it just should not play out the same way every time.
Rockstar introduced Jason and Lucia after an easy score goes wrong. Beyond that premise, it has not explained how robberies outside missions will work, so this is just a community discussion.
What would make you think twice before pulling the gun? More money for more risk, witnesses who might recognise you later, an escape you actually have to plan, or something else?
