After I've had a few days to play it, I highly recommend the Tiger Woods 2003 game. It looks as good as any game I've ever seen for any system. It's fun, but there's a nice balance between arcade golf and actual simulation.
It's excellent, and my wife enjoys playing it too. We're playing the mode where you start out with a rookie golfer and everytime you get a birdie, hole-in-one, chip-in, etc. you earn money, which in turn can be used to upgrade your ability (if you ever played Baseball Stars on the NES where you upgraded players after each game, it's similar to that). Awesome game all the way around.
