Thankfully, there's a lot to distract from the streets. The clockwork crowds roaming them are a lot more responsive, and will actually crowd around and hoot if you start a fight. They'll also get up to less friendly dealings, and you'll often have the chance to foil muggings and earn a little reward.
The shopkeepers you'll lean on for protection money - your main source of in-game income - have a little more depth to them as well. A lot of them can still be bullied into submission by smacking them around or pulling a gun on them, but all the new destructible objects give you inventive ways to destroy their businesses and get them to play ball. And sometimes, they're actually eager to make a deal, provided you'll just go and do something nasty to someone who's been harassing them.
