With consoles and PC's more powerful than ever before, I'm begging for more interaction with the buildings, or maybe just half of them. How great would it be to be able to walk into any building and interact with people inside office buildings, have cops chase you up massive skyscrapers and hold them off in the hallways, only to parachute out off the top to safety. Another feature would be the getaway, they have this option available in online heists but not free roam. For example, having an option to rob a full scale bank like you do in heists, by yourself, and having a getaway already planned in advance.
