A good game for the genre. Don't play it if you're not into flight sims at all.
The only let down is that flying with the keyboard is pretty hard, or at least trying to shoot someone down is. Unless they are flying completly straight you'll really have a hard time shooting enemy planes down. I wish the game offered more customizable control settings, like maybe using the mouse to fly like in BF1942. You won't have a problem if you own a joystick or something similar though.
Another let down is actually the sound and voiceovers, it's pretty annoying to hear your wingmen yell at you over the radio just because you don't fly how you are supposed to every two seconds. Plus i dont understand this big hype about having russian or german talk over the radio, wouldn't it be better to listen to someone speak in english but maybe have somewhat of an accent like in every other game? And not be so freakin ripetitive?
