Some great ones on this list! I enjoy being able to play "famous" courses, but also would love to see tracks that are unique and stand apart from the same courses in all golf games.
Wisconsin:
Sand Valley
or
The Lido (a lost CB Macdonald course being rebuilt)
Minnesota:
Hazeltine National (yeah, in past games)
Windsong Farms (Have played Hazeltine and WS, Windsong is far superior)
Oregon:
Crosswater (has held many PGA events, NCAA champs and more)
New Zealand:
Cape Kidnappers - Hawkes Bay (Dramatic cliff course)
Scotland:
Machrihanish Golf (Timeless Underrated Links Course)
Arizona:
Whisper Rock - One of the best maintained courses I've seen.
