I agree. In simming days gone by, the norm was to model one, and only one, aircraft, with the intention being that you got as much fidelity as possible. To complain about the number of planes in LOMAC (especially since you get new ones with every expansion pack) is, in my opinion, rather short-sighted. I think there are some people who will never be happy no matter how many planes are made flyable ... just look at the IL2 and Pacific Fighters franchise; there's about 100 flyable planes available now, but there are still people on the forums whining about how this or that plane isn't flyable. I have an inkling that it is these same people who are happy to install the 'fly any plane' mod in Falcon 4 - the cockpit is that of a Falcon, as is the avionics and flight model, yet they're happy to believe they're flying something different simply because the 3D model and skin is of an A10 or something.
Personally, I think it is dangerous to put so much emphasis on making so many planes flyable, as you run the risk of reducing the fidelity of them all, and in addition, you take away valuable programming time that could be spent fixing bugs, improving graphics, or even (dare I say it), improving the campaign engine. I'm happy that 1.2 is introducing only one new flyable aircraft (although I'm especially happy it's a helicopter; just how long has it been since the last decent helicopter sim?).
