I think the simulation part of the game AH should have various levels of realism, user selectable.
If the more realistic parts of the sim makes it more difficult, so be it. Choose what level your comfortable with, and go flying. .
If gun heaters load up and adversley effect you alternators or whatever they had, and you select them off acordingly, your next bounce without turning them on might end up in some problems. I'd like to manage the engine a bit more instead of hitting "E" and leaving it on 100% for the next 20 minutes. Oil soaked windscreens, historic ammo counters, be forced to do small sections of IFR, navigate, each respective aircraft had proper guages in historic measurments etc... would be nice.
As it is now, the best pilots in AH couldn't get in a real 109 and find the start switch, let alone get it running. Unlike many commercial airliner sims, where after many hours in them, you in fact could start them taxi, and away you'd go. It would be cool if a simulation was detailed enough that looking at the real deal you could know what most everything is.
Do I want to have it so realistic you sit in a meat locker to simulate the cold for 8 hour rides back from a bombing strike? Heh, of course not, but a Lanc mission takes about a good hour in this game and it sure be cool to have all the goodies modeled to play with along the way.
If HTC had unlimited resourses to implement such things, (and they don't) I still can't say they would, but it would be really nice.
