Recommended to fans of military aviation of the 2nd World War. This simulator allows to control a combat mission virtually all models of this conflict and qq experimental models, as well as hunters bomber. Realistic without sacrificing playability and offers several game modes: single or multiplayer, fast part in campaign mode. Personally I installed under XP or 64-bit Windows 7 without problems. It runs smoothly on current machines and older machines. Icing on the cake: the price which makes it very affordable! So I recommend it without hesitation.
