Releasing a new course here on WGT takes over $200K and 6 months minimum.
This isn't something that a bunch of graphic artists can sit around and draw... these backgrounds are HD photographs from the actual courses.
Getting a new course here is like mating elephants... It's done in high places, there's a lot of yelling and screaming involved, and it takes two years for anything to develop.
Besides.. it looks like Oakmont and the back side of St. Andy's are next in the bull-pen.
Peace.
