Tiger Woods PGA Tour 06 for the 360 is similar to current gen versions with only minor tweaks and improvements...
The biggest addition to the game when it was ported to the 360 is the graphical improvements. The game looks way better than the older versions in mostly all aspects. The courses look terrific with blades of grass sticking up in the rough, the water looks fantastic (especially along the ocean at Pebble Beach, and the player models look much closer to their real life counterparts. I was amazed at how much Retief Goosen looks like himself in the game, even his expressions...except the angry ones as he hardly ever gets angry in real life.
The other big improvement in the game is the raised sensitivity of the thumbsticks making shots go off-track more often than in the older games. The transition at the top of your swing is also more sensitive with only a slight pause causing you to lose distance. The ball flight also seems to be more realistic making using the shapestick a necessity (especially to get over those bunkers). This added challenge makes up for the loss of Tiger-Proofing which often lead to ugly courses anyway.
Power boosting has been made far more challenging than ever before. They used the left bumper for power this time meaning you'll have to use your right hand on the left side of the controller. This in itself can make your shots far less accurate leading to shots that actually go into the rough...hard to believe with the other versions of this game being so easy.
Putting has remained the same using supposedly both thumbsticks, although putting with just one is fine for most situations. Putting is pretty easy unless you have it on professsional difficulty and have the green hardness and speed turned up, this can make the putting system far more delicate making missed putts a common thing.
As for a story mode, there really isn't one (One of the features dropped). Your character you create plays in a Pro-AM..well not really, just one hole. You then start working on getting to the PGA tour by doing a series of short challenges. Once on the PGA tour, it is really just a bunch of tournaments like in previous versions leading to extreme boredom.
Luckily the online mode has returned leading to more value in the game. The online portion of the game is simple to navigate but it's often hard to find a match without lag. There are also online tournaments to compete in, although you never really see the other player, you simply play by yourself and you score gets posted. Be warned though, the tournaments are very hard to win unless you're a TW master as winning scores are often 40-42.
Overall, TW 06 for the 360 is a great game of golf. This time around it may only have 6 courses (Beautiful looking I should say), no Tiger-Proofing, and no real Story, but it more than makes up for it by having an increased difficulty and better looking visuals. For this game I'd recommend a rent before you purchase it, but if you really want a good golf game go ahead and buy this.
