I don´t care if the course is real or fictional when playing out of tourneys which I do more often.
I designed both kinds, and the real ones took me like a year and was a real pain to do trying to copy the original without the lidar and stuff we have now. The fictional ones were a joy to make, using all my creativity and trying to transform what I learned about course strategy and seeing great holes from magazines and broadcasts. Sometimes I got so inspired I could not stop and stayed up all night and created three holes in one session.
