Tiger Woods PGA Tour 08 looks great - there's no question about that. But what really makes the game impressive is the Photo Face feature. When creating your character, you can import a digital photo of yourself (I assume you'll also be able to use the new PlayStation Eye when it releases) and map it to your character. It is really neat to see how well the photo is mapped to the model and the end result is pretty accurate (provided you begin with a good picture and do a good job adding map points). You can further customize your character by adding hairstyles, clothes and other physical features.
Beyond the player-creation, the game looks incredible. Golfers are really detailed, right down to little mannerisms that add more life to the digital characters. With the exception of spectators, who look blocky and blurry, the courses look good.
Sound is the presentation's weakest link. The commentary is lame and overly-repetitive. The jokes aren't funny and will probably have you rolling your eyes more than laughing. Music isn't much better, but thankfully the game is mostly quiet...
