Marco129: You will find that each time you advance a tier, your game will "fall apart" because you a playing with a different set of programmed parameters.
In more detail, the greens will become faster at each tier until Tour Pro (more sensible to slopes), and sometimes the tees will change to longer tracks. Keep your attention on these parameters!
And the game will become more difficult, higher winds, less forgiveness...
...more challenge and more fun! Just invest some time and/or money in this leisure.
Have fun!!
