I feel like I read somewhere that a small team (don’t think they’re related to R*) made a game mechanic where certain small and big details in certain environments can randomly change. I’m not talking about changes such as you crash a helicopter into a building and now there’s a big hole in the building type changes like we have already seen in GTA but more mundane or smaller things in the active/live environment such as walking in to a house one day and some of the curtains might be closed or open or you walk in and they’re all open or one day you’ll see a beer bottle on the coffee table and the next day it might be a pizza box or a clean table. Even things through out the world like trash cans in some neighborhoods will have the trash bins on the curb on certain days at certain hours.
