Some of the comments here are nearly laughable. Realistic? It's a VIDEO GAME. How realistic is it that I can play for a couple of months and now consistently shoot in the high 60's at St. Andrews? Would that happen in real life? Has anyone been watching the Open?
And then the comments telling people that they have no talent. Hilarious. Again ... it is a VIDEO GAME. Those who rip others for not being as "talented" in WGT as they are probably the same person who has never shot below 100 in real life.
And finally, to the OP ... I agree, it can be frustrating, and I'm not going to tell you how to think or what to feel. But in my experience, I remember being a hack and shooting in the 80's against Pros who were shooting low 70's. I thought that was going to be unobtainable. Now, I just got Master status and shoot in the mid 60's - low 70's more times than not, and I sometimes play against people who smoke me. I don't get all bent out of shape over it. I just try to improve. I watch what the better players do, and try to replicate their good shots to complement my own play.
As far as dividing the field into different groups for tournaments because we have some folks who are VERY, VERY good at this game is also a mistake, I think. At the US Open did they have a separate tournament for Tiger, Lefty, and Stricker ... then the rest of the field? Does Wimbledon have a separate tournament for Nadal and Federer, and another for the rest? In real life, the best way to improve your game is to be thoroughly challenged. Whether that is by tough conditions or against the best players out there ... it is all the same.
In the end ... this is a video game. It shouldn't be 100% realistic ... if it were, I would be shooting 80's and 90's and breaking clubs. If the game causes too much stress in your life because you feel wronged every time you play, then maybe it is time to move on to another source of entertainment.
