Jane's Combat Simulations: WWII Fighters

You get to fly either as an Allied or German pilot during World War II. You'll only get to fly fighters, but the selection is very good, ranging from the FW-190, BF-109, and Me-262 to the P-51, P-47, P-38, and the Spitfire. There's a lot to learn, but it's very easy to get in and fly. You also have the option of playing single missions or starting off on a career.
