Well... dreams... I dream about all these things:
A long dynamic campaign - your career through the whole war to its ending... including maps of the west and middle Europe... aircrafts like Tempest, Typhoon, FW-190 D, Swordfish, american planes, more ships, submarines, carrier like the Ark royal of cource
The Mediterranean maps, missions in the North Africa, real battles like Taranto attack or the battle of Malta... of course!
Visual things: photorealistic clouds - all the kinds of clouds you can see in the sky. The seasons changing through the campaign - summer, autumn, winter, spring... with green fields in spring, yellow corn in summer, colored trees in autumn and snow in winter... different sea conditions like bigger or smaller waves...
Life in the airfields! People walking, mechanicians working and - in case of the emergency landing - ambulance car and the fire fighting truck coming! During the start: a man showing you the way to the runway!
