In a previous post, there is answer on a Architect Course Game. The best I know is the APCD (for Arnold Palmer Course Designer) which is delivered with the Microsoft game : LINKS (last version: Links 2003). There is a big community of Links nuts (Linksters) on Internet : players of this golf simulation and also, architects who use APCD.
With this game, you can play on great real courses : Bethpage Black, Pebble Beach, Spyglass Hill, Kauri Cliffs, GlenEagles, St Andrews, Merion, Colonial,...
To give you an idea of the realism of this game, here is the link for some pics of Augusta National:

APCD architects create too some fictional courses. Here is the link for some pics of Mike Jones (best APCD designer in my opinion) last design: Rugged Dunes. I think you are going to love his "natural" design
