My suggestion is to add parkour and along side it a dense urban map to basically act as a playground to run around in and also roads for driving however the main thing is the parkour. The parkour system would work kinda like assassins creed nexus if you’ve played that, you would have the ability to make perfect jumps from platform to platform if you held a button that didn’t already have a use (so basically they A button I believe which is already jump would be short hops and the say Y button would be for parkour and longer more precise jumps). Also you would have the ability to scale walls and buildings as long as they had handholds (so people aren’t climbing everything that the devs didn’t intend) as well as the ability to swing from poles.
