Without a doubt, the best and most realistic sports game ever.
Forget just sports games, it has the best controls any game has ever had. Period. The Wii Motion + makes the latest installment of PGA Tour absolutely phenomenal. It requires the player to use a much more proper swing, unlike in other versions where you could swing wildly and get a good result, or a slight turn could cause the ball to draw or fade massively. It was entirely unpredictable. With PGA Tour 10, it gauges the exact degree you've turned the Wii Remote, and adjusts draw or fade accordingly.
Going beyond just the controls, it's even realistic in terms of the weather! Yes, it works in cooperation with The Weather Channel to simulate the course's actual conditions, down to the wind speed and how sunny it is. With this comes many new modes, Play the Pros, where you can compete with the pros in real time as they play in real tournaments, under the same conditions as them, and the Tournament Challenge mode, where you compete in past tournaments and try to essentially rewrite history (for those with an IQ below 80, said mode will not literally change the past and end your existence).
The career mode is excellent, and the replay value is massive due to almost 30 different courses and online play. Plus, there aren't many games that are better for parties. Once typical golf bores your guests, just switch over to party mode or disc golf (I haven't tried either, as the main game is plenty to keep me satisfied).
All in all a fantastic game with endless replay value.
