I just finished reading the whole thing (google translated) and all i can say to the team is "Thank you, you guys rock".
It seems they managed to include a lot of what various people have asked and also make it optional, so that everyone will be happy.
Imagine entering clouds and when you get out of them your canopy is all fogged up. You turn on the de-icing system, but before it manages to clear it up, BANG, you get bounced. You break hard and dive back into the clouds to escape and determine the amount of damage you received. All seems to work well but the screen goes darker gradually, you take a look at the lower right part of your BF109 cockpit and you see the oxygen pressure is almost zero. That lucky guy must have hit your oxygen lines with his hail of .303 rounds. As you monitor your engine for signs of carburetor icing you decide to remain in cloud cover for a few seconds more, then dive fast below 3km/10000ft to make sure you don't pass out from lack of oxygen. It's time to head back to Abeville.
In the time span of less than a minute we have an environmental effect resulting in a debilitating state, pilot action to remedy that, surprise attack as a result of that action distracting the pilot, use of the environment to escape, damage that is not immediately visible nor crippling to the airframe, but which will still creep up to kill you if you don't expect it and know what to look for, plus a Hurricane scoring a mission kill with its puny .303s, all in all a more "like the books we used to read" experience thanks to the new features. Plus, the lower caliber guns are no longer useless when there's lot's of small, unarmored things to break like hydraylic lines and such.
Somebody stop me, strap me to a psychiatrist's bed and dress me in a straightjacket, because i can't contain myself over how awesome all this new stuff is
