I imagine the developers have considered this, but I also imagine that they have considered that future courses could give some extra money for future development.
I would however be willing to splash some cash for a great course designer and wishing for a community with great courses.
But I am also a bit divided on this issue.
If if PP would release courses frequently, I might be content with that, knowing the quality would be superier compared to most amateur-course creators.
The problem with PP producing courses could be that most of the greatest real courses would probably not be available(if released by PP) due to licensing issues, and what is a great golf game without St Andrews and Pebble Beach?
Anyway, thanks for the best golf game in a decade.
