jjjj035: Like other golf simulations, I pretty much reached peak 'skill' after a few days, and the vast majority of improvements came from better equipment and learning the quirks of the game and specific courses.
As previously said to you one thing you have not done is reached peak skill, not unless you define that as the level you cared to work for.
The last real golf game that captivated my imagination was Sega PGA circa 89/90. Great game back in the day, but yes a limited shelf life. I missed the others as much as anything due to kids being young, and I was busier with them.
WGT has certainly had it's issues but remains a very challenging game. It does need a good boot up the backside in several ways, and maybe some extra funding will help...... Felt like being glass half full :)
