There isn't that many holes. The different holes are very imaginative, with clever animations and sounds. Many holes have running commentary as you play. The on screen strength meter makes it easy to tell how hard you're hitting the ball. The aiming line makes it clear which direction you're headed.
Graphics are excellent, sounds are good, too.
Game can be loaded in a lite or full install mode. In lite mode, you need about 40 MB of disk space, and you have to wait while the system loads each hole as you play it, which takes about 15-45 seconds. In heavy mode, I assume that the entire hole is on your hard drive, so it loads quicker. You can choose front 9, back 9, or all 18 holes to play.
