I found IL2 on one of my disks for a video card I got a while back...
loaded it, spent 45 minutes figuring out how to map just a few buttons and 4 views.
FM was the worst I have tried. I know I am no real pilot, but I have taken 1 flying lesson and did everything except actually land the plane (I did work the rudders 100% of the time from taxi to being airborne and had the stick about 50 feet off the runway)
from my one experience the FM in IL2 is so "over modeled" it is almost arcadish.
also the map was almost impossible to read, and the "overcast" sky was an eyesore. there was NO feeling of altitude, 500 feet or 5000, I couldn't tell.
