Regarding the sound of il-2, I've replayed videos I recorded at Duxford and the sound sent shivers down my spine, then I fired up il-2 and it sounded like, well, not nearly as good. I can make it sound ok, but need to tune my sound system for it, and at these settings, nothing else replays well. So, it's not all in the sound system.
I've also played loads of racing games and none could match the sound I've heard on the racetrack, it's something very hard to reproduce on a computer. Unless you want to be at war with your neighbours.
