Firmness is a global setting for the current course you are creating or editing in the Greg Norman Course Designer. It affects general terrain, heavy rough, light rough, fairway and greens and refers to the amount of ‘bounce’ or ‘kick’ a ball might get when it lands on the ground.
Looks fantastic! I'm ready anytime they are. I already have my psn store act loaded up to $40. Haven't been much of a golf gamer for the past decade or so, but the apparent depth of this title has sucked me in. The last golf title I played for any period of time at all was Links 2004 on Xbox.
