Bronk, seriously....
as long as you preface everything with "for profit motive" you completely undermine any claim of realism and accuracy. If profitability is your #1 priority, and not fidelity, you cannot have a sim... the most you can hope for is a popular game; and AH has been successful on that count, certainly.
"...as long as there's no benefit [to engine management]?" Like, say, having your aircraft actually perform properly?
It's also optional to use your stick and rudder, and to coordinate maneuvers, and to fire the guns when you want to do damage... when it gets right down to it.
