Got my copy today nad I've played 72 holes so far. Here's my impressions:
First of all, the graphics aren't rock-your-world awesome, but they're not really that bad, either. There are a lot of nice little details here and there. The graphics don't take away from the game at all.
Second - swing mechanics. They are actually pretty close to right on. But, it takes getting used to, and I think I finally figured out why that is. The swing action will mimic a golf club fairly faithfully, but you have to remember that a golf club has some weight to it. A Wiimote can't give you that same counterweighting, so it is difficult to match the speed of an actual golf club until you get the hang of it. (I think Wii Golf actually does a pretty good job of compensating for this, and EA should take some notes there.) Once you do get the hang of it, the game becomes a lot more fun.
Third - putting. This is where EA needs to put some work in for TW 08. It can be learned, but when you have those faithful swing mechanics, the putting should too. Instead it's a matter of waiting until the on-screen golfer has pulled the putter back far enough.
So far, though, I am enjoying the game a lot, otherwise I wouldn't have played four straight rounds of it.
