I've been revisiting GTA IV recently and here are some things that really amazed me that I don't remember seeing in GTA V. I would love to be wrong and for these things to be included in V, some things I noticed were
-Peds drinking coffee
-Peds either working on their cars on the side of the road with the hood popped open, or loading things into their trunk
-Cars being pulled over on the side of the road by cops (not just police chases, but encountering a car that has already been pulled over)
-AI cars actually park and a pedestrian gets out and starts going about his/her day, meaning the AI cars actually have destinations that they reach.
AND this one was the kicker for me. I was attempting to kill playboy X and shot one of his henchmen in the stomach until their health was empty, he fell to the ground and cried out "I'm done, I'm done, next move is yours gangster!"
This made the gunfight feel so much more personal and visceral than I can ever remember any shootout being in GTA V, is anything like this featured in V?
