Another comment about the gauges, while agreeing with the aforementioned difficulties. Making SA possible by having as little visual obstruction possible on a such small, 2-dimensional screen makes the game playable and enjoyable.
But a further thought about the new gauges. I guessing here, but from historical reference it seems most real life combat pilots fly only two, three or four different aircraft on average during their entire careers. And none of those at the same time. This means they can learn the layout of gauges in each aircraft quickly and intimately. In our cartoon game, I suspect that a pilot taking up ONLY four aircraft in one day is probably in the minority. I'll bet for a great, great many if not most, it's not unusual to fly two or three different aircraft, from different countries within the same plane type, and to often fly fighters, and bombers, and attack planes.
Certainly, we eventually become very familar with our top two or three rides, but even so, if they have completely different layouts, it's still disconcerting. And giving wanting to take less used rides fairly often, it can be difficult to fight well if the cockpit gauges are different in size, orientation and format.
I would suggest standardizing the most important gauges at least (within a historical-looking dashboard), regardless of historical accuracy, simply because we can get into so many different planes on any given day.
