Its a lot of fun. The close-in guns-only dogfights are worth the price of admission. The graphics are better than average and the damage models are fairly advanced. There are LOTS of add-ons available since the sim is open source. Best of all, most add-ons are very high quality. These include paint jobs, new terrains, new weapons, and lots of new airplanes. Make sure you load the first patch.
