The golfers are simply generic golfers, but they look fairly realistic. This lifelike appearance is helped along a great bit by the game's ability to mirror the player's movements. Once I knew that my on-screen persona was going to mimic my movements with a reasonable amount of accuracy, I found myself concentrating more on my stance, position and swing, rather than that of my digital accomplice.
Just because you won't be paying a lot of attention to your character doesn't mean that the game skimps on animation. The golfers will analyze the next shot a bit before some of the shots, much like golfers do in real life. Unlike real life, you are treated to a fly-over of each hole before playing it when playing a round of golf. Not only do you get a visual description, but a narrated one as well.
The voice acting takes the form of a coach, whether you're in the tutorials or having the next hole described to you during your flyover in a game. You'll get some good advice from an informed guide. I did find that when I messed up a hole or two... okay, got my fifth consecutive double bogey... the coach would tell me to cheer up and that I could still turn it around - even when I clearly couldn't. A little bit of positive thinking is a good thing. Too much can be downright annoying.
The ambient sound and accompanying animations add a nice touch in Real World Golf. You'll be playing a round of golf or practicing at the driving range when you'll see and hear a bird or an aircraft fly overhead. These may be little things, but it's the little things that help to convey realism.
