There is another aspect which I have seemingly enjoyed mentioning over the past years...maintenance and accidents. Look at the F-105 service in Viet Nam...some people can quote losses by SAM v. AAA but look at the proverbial next column, that of accidents...staggering.
Often I have trumpeted for iL-2 series (no where near perfect) but the game apparently had a random generator that would cause accidents at times (nursed my flight of beloved La-5's all the way home after a fierce tangle with butcher birds only to lose 2 in a collision in the pattern...from all accounts that was more common than movies would lead one to think).
Sometimes one takes off, does air to air refueling twice and then lands after converting fuel to noise for a few hours...and that would be mission accomplished. A good mission objective is same number of planes land that took off. Doesnt sound very "silk scarf" does it?
But I suspect that the buying public would not dig flipping circuit breakers, memorizing emergency procedures (in multiple aircraft, but that is a different story) watching a jumpy oil pressure gauge for 4+ hours or filing paperwork/forms/briefings/maintenance logs.
How about a game where you have to work your way up from a mighty T-6 Texan II (and go through academics for months before you even smell that weird asbestos/sweat/puke aroma that has been accumulating for 30 years)? Then the briefs, forms, logs, paperwork, and by the way you have another job(s) to do within the Squadron as well? Oh, and then you get sent to a staff tour?
Think about it...
