I was also surprised how easily I found the ground targets. I think the draw distance was slightly increased compared to the demo but I could be wrong.
However, finding them in the streets of Berlin or those bunkers in the Ardennes (single mission) is still close to impossible. Had to fly these missions on realistic mode first to know where they were actually hidden.
I second the cockpits for the 109's and 190's - absolutely essential. If there was a DLC offering all missing cockpits I'd be crazy enough to pay up to 20 Euros for it. I love the German jetfighters and having no cockpit view (and most likely never a DLC to fix it frankly speaking) sucks.
I still cannot believe what I hear about the kill system (couldn't find games). If you damage a plane badly enough that its pilot can't keep it airborne you
have to get the kill.
