As frustrating and rewarding as real golf. The best golf Sim you can buy.
The swing technique is the main attraction to this game, and it works! For those who say it doesn't work right, thy need more practice, just like real golf. Sure it can be frustrating at first (just like real golf, again). But it also has it's rewards, when you hit that sweet shot, right next to the pin from 200yrds out.
The feature that I find extremely appealing, besides the swing technique, is creating your own golfer and working your way through the ranks. You're going to start off as a rookie, and in doing so, your not going to be a Tiger Woods right off the bat, in fact your gonna suck. Your going to be inconsistent, but you'll still earn valuable points to upgrade your stats, as well as money to upgrade your gear.
Golf is a game of skill, patience, risk & reward and I believe this game encompasses all those areas.
For those who want the more traditional feel, or just want to sit down and play, there is a nunchuck option that works very well too.
