1) In a War in Europe or WW2 scenario, the game engine decides air superiority/interdection effiency for the entire scenario. In actual fact, there was the Russian Front, Afrika/Italy, and France, not to mention the Pacific. Air superiority in France certainly had no effect on air superiority in Russia.
The Air Superiority, as stated in the air briefing is nothing but a rough guide for the player. If I am playing EA and I want to know, globally, who has more aircraft on air superiority, I look at the briefing, because that's all it tells. However, local air superiority is determined locally. ie: my paras get interdicted by air craft that are in range, evidence of this being: take a para from England, fly it to Norway, if you still have control, there is very little chance of it being interdicted. Now, do the same, btu fly it over Germany. Damn near definate chance that it will not make it to its target early in the war, because of the mass of German aircraft.
Another thing is looking at the detailed combat reports: How often, when fighting in the east and the English fighters are in NA and England, do you see English fighters covering a Soviet attack? Never. Why, because they don't have the range and therefore do not fly air sup missions over there.
Furthermore, the interdiction level in the air briefing is also just an indicator. Interdiction levels are also determined locally.
Specifically to Macgror's comments: A) 2 to 1 air sup over Poland in '39. It would appear that the Allied player is using his air craft very effectively, placing them all in Poland, or you have placed your air craft very poorly, with none close to Poland.
B) The situation in Norway sounds like the Allied player is using his forces very efficiently, placing masses of fighters in Norway. However, if this is the case on the first turn you have attacked Norway, you may wish to mention to your opponent that they should not be placing air craft in Norway until after you have taken the DoW theatre option, as placing air craft there before hand, or turning the Norwegian fighters to air sup, would be against the house rules.
Further, I would like to here Jamiam sum up just what they changed on the air model, as, if I remember correctly, they changed the effectiveness of things like AA, and did nothing to the ranges of air craft.
Macgregor, I would love to see some saved game files form yourself and your opponent, so that I could offer more imput as to exactly what has caused your current air superiority problems. If you cannot zip and attach them here, my email is veersw (at) gmail dot com.
Lastly, I say this all in a very non-combative way, as I would foremost just liek to clear it up.
To repeat history in a game is to be predictable.
