Here is an incredible look at golf in Korea. They have the highest per capital rate of golfers — most never hit a ball on a 'golf course' but are just as keen about golfing using simulators.
Not just a chunk of artificial turf and projected image of a fairway on the wall with a net to hit into, but high tech tee boxes with multiple kinds of turf to mimic fairways, rough, and deep rough as well as real sand traps and putting greens that can change the slope so you can practice specific types of putts. All with realtime feedback so you can see what you have done and why.
