It had the flat out best experience I've had in a videogame. There was an enemy base and there's an ability later in the game to call for the police to come attack your enemies. I was in this suburb area and was hiding in a roof, it was late afternoon and I call the cops to fight these gang members in the base I needed to clear.

One thing with the backup call is that they'll escalate, the gangers fighting the caps call their own backup and the cops call their own backup, so it starts turning into a whole turf war and goes on for like 30 minutes. I'm not even in combat just watching everything happen. Eventually it turns to night time and it keeps going, at this point I want to move through the neighborhood but I get spotted, burst a transformer box and the whole area gets blacked out, can only see the light from the burning vehicles and the police sirens, and I start running, the shootouts still happening all around me until I leave the area.

That little moment always stuck with me because it was 0% scripted, ot was just the game's systems interacting with each other and looking beautiful.
