Some fine posts here gentlemen and two great examples, X-wing was fantastic for sucking you into the game, a great feature in X-Wing which i really hope Oleg allows in SOW was being able to change the pilot roster, you could put the names of your friends into your squadron which gave you that extra zest to save your AI wingy. Also EAW was a very absorbing sim, and like Blackdog as already stated it was fantastic to see formations of bombers coming in, I really hope SOW manages to capture some of these things.
