You will never be prepared for the noise vibration and feeling in RL flying.
IL2 sterilizes those sensations into no more than a desktop 2D experience with some procedural button pushing and stick waving at best, the rest is all about gaming the game, its not a simulator,
but it can give you some thrilling experiences with a busy Teamspeak and your fellow pilots screaming for help.
There's lots of different people in squads and flying solo who use the game to suit their needs with CooP's or DogFight missions.
They are all entitled to fly how they see fit and how they interpret the way it should be for them.
