And on the subject of realism, let's not forget the bunkers. They have been somewhat lazily programmed so that the position you are in dictates the amount your ball is plugged. At Kia and BPB, you usually get lies 20/25% or better allowing some height and spin to the shots. Everywhere else you usually get 30/40% lies, ie. nearly half-plugged.
It would make for a more golf-like experience if the angle of entry of a shot dictated the chance of how plugged the ball will be, with an element of randomness like real life. The steeper and harder it lands, the higher the chance of it being plugged to a greater degree. If a ball comes to rest after rolling in the sand, it will never be plugged. Courses with more hard-pan sand like Kia can then be assigned lower % chances of generating plugged lies.
