I agree about 15. I kept thinking I should be able to avoid or dodge attacks and it just didn't feel as good as it should have - same with the car, actually, in that it just never felt as satisfying as it could have. I prefer the feel of 16 or 13 (or even 14) to the weird hybrid that 15 was that was unsatisfying on both the action and rpg fronts.
I did like some of the small details in 15 like the pictures, though.
