I have already said this is the best looking game I've seen, but you got to admit that the second half of that set-piece wasn't that crazy compared to stuff you did in previous games.
For example, compare this to the horse ride set piece in U3 (

The full set piece was incredible, but I think that the first half with the market shootout and later the drive-able jeep where you could take different routes showed a more significant evolution with mechanics as well.
The second half wasn't anything we didn't see before in the series, only obviously looking much better,
