I thought I'd chime in here, just to give my two cents.
If you're looking to make the game feel more like real golf, I wouldn't recommend limiting the information available to the golfer playing. From my yardage book and laser, as well as GPS Apps and Google Earth, I am able to find exactly how far it is from any point on the course to any other point, which is important because it's not only the current shot that matters. Planning ahead (so I don't have a half wedge into a tricky green) is just as important as the current shot, so knowing exactly how to measure these things is, in my mind, MORE realistic.
Having ambiguity in the aiming process, and exact precision in the shot process is the opposite of what makes golf fun and strategic.
On the golf course, I pick a very specific point (the limb of a tree, or a patch of grass in the distance, and then execute an imperfect swing to a perfect plan.
In The Golf Club, can only execute an imperfect plan (without all the information I need), but the swing is far too forgiving. This is why you see extremely low scores.
On an average well struck drive, your PGA Tour player carries the ball about 275 yards, and still has about a 6 yard miss on each side if he's trying to hit the ball perfectly straight. So, if you want to bring some strategy into the game, even a perfect swing has about a 12 yard "circle" instead of a pinpoint accuracy to land in.
Imagine if you had to make the choice to hit a driver knowing that even a very well struck shot still has 6-8 yards (generous) variance, just like in real life.
Same for all parts of the game - iron contact, which has distance variance too even on perfect shots, wedge spin, even sand shots and such.
THAT would make it more realistic, and in my opinion fun, because you can plan extremely well, but you have to plan for your misses, which is the thing that makes good golfers great in real life.
