In real life golf courses cannot be locked or unlocked. Your terminology tells me you might be a serious video gamer. I can tell you that WGT is a bit more lifelike than most video games and requires some acquired skill and even some skills you would bring with you from playing the real game. Reading the break of a putt being just one of those.
The game can be quite frustrating for the "gamer" who has never played the real game.
Beware.
I've been wondering about that If having experience playing the "real game" gives one an edge. Especially in putting, I suppose. Its hard for me to read putts because monitors are 2d and in real life one reads putts in 3d, I guess.
I never played golf. In fact the only time I ever held a golf club I put it through somebody's windshield. They had it coming.
