I've been a flight sim nut for 20 years and I can assure you that it's the best simulation of fighter aircraft to day. Although it's highly scalable, it is best enjoyed on a very high end machine (read 2.8 GHz with ATI 9700). There are some great training missions but it has a steep learning curve. If you think of it as a game, you may be disappointed. If you think of it as a flight simulator, you'll be tickled. It is welll supported too with a team dedicated to providing patches if necessary.
