What's been bad? I'm happy to answer questions once I get a good look at it tomorrow.
It runs really well on my machine, but I have a pretty grunty rig. The commentary is mildly amusing, I could see it getting boring if there isn't variety, but I wouldn't place any importance on that aspect.
Other than that, it's exactly what I was hoping it would be. A modern non arcade type golf game. From what I've read, the course maker is supposed to be pretty intuitive.
I'm not sure why it has average reviews. It's a great little golf game if you ask me. Only issues might be that they are fictional courses. Even then, I'm not sure if they have real ones yet but there is a pretty good course maker, I'm sure someone's made some "real" ones.
