You can even create your own missions - decide which plane to fly, against whom, how many of planes you want in the air with you (friend or foe). If you want a mission prepared for you, it has many options for that too: Allied or Axis combat or even training missions to choose from.
It is set over Belgium in 1944. Other aircraft is not the only obstacle you face in combat, as the game sometimes has anti aircraft flak exploding around you as you fly high above the clouds or low to the ground, dotted with woods and little towns. (You can even choose the conditions you fly in - moonlit night, dawn, dusk, or high noon. Inclement weather or clear.)
With this game, you can fly against German or Allied fighters or bombers (Junkers, Heinkels, Flying Fortresses, and others). You can view the action from the cockpit (and even fly by instrument), or follow your progress from angles outside the plane. You can also "test fly" any plane on limited strafing missions or aerial combat.
For an outwardly simple and inexpensive game, the "World War II Fighters" is a lot of fun. You can even hear the voices of "other" pilots in the sky. Germans if you are flying a German plane, American or british accented english when flying either of those respectively.
If you want to see the cockpits in detail, and get a sense of flying each of the planes, this is a good little game.
,really fun when I get in the Focke-Wulf 190.
