This game is exactly what you want in a golf video game. The courses look amazing, the controls feel as close to golfing as you can get without having a real club in your hand, the multiplayer works very well.
The other modes are okay, I guess. The disc golf part is amusing, but not that filling; anyone who plays for real will be bored after a few holes. The party stuff I didn't bother with.
In short, if you like golf, you'll get this, because it's the gold standard for golf, and the Wii is the best place to implement it. If you're looking for high-action crazy golf, Super-Swing might be more up your alley.
I remember when this game came out on PS2. Watching people slam the analog sticks in one direction or the next to get a maximum roll all the ball. I never actually played it, no real reason. However, this version, with the Wii controller used as it is, works perfectly. There are lots of tiny details to learn to improve your swing, or you can just swat it. Up to you how deep you want the game to be, or how simple. Graphics are good enough for the game, and the fact that it links to the weather channel on your wii and makes the game play the same as the weather outside your door is great. I'm not sure if this game will make me a better golfer, I doubt it, but it's still very entertaining.
