I think it all boils down to the normal human desire for bigger, better, MORE !! Higher speeds, faster climbs, and more cannons, its a natural progression.
And the "uberplanes" as you call them are the pinnacle of developement of the planes most of us were weaned on, from birth. These are the planes that "won the war" or "almost turned the tide" depending on your perspective.
For instance my father was in the AirForce as a Navigator. I practically grew up on a base that has a P-51D sitting right by the front gate, so it means alot to me. FYI my unit (I joined it when I was old enought) was one of the last units (maybe the last) to actively fly the P-51 for the USA (WV ANG, 130th TAC Airlift Wing now).
To be honest, very few people identify with those early war birds.
However I can understand the desire for them since they are different from what you are use too.
But lets be honest? Do you expect HTC to go from mostly Latewar planes to early war planes? In my opinon thats not likely since this is the "niche" (uber/rare planes) that they have gone for to distinguish themselves from the other sims, just like WWIIOnline has gone initially for the "total war/early war niche".
My feelings are that, given the initial track of developement, HTC should fill out the late war set entirely, and
then start working their way back. And fill in the set.
Realistically, until we get to scenario's or some sort of rolling plane set, the early war birds just won't get flown.
How many people fly the 109F now? And how many will fly the Spit V or C.202? Not very many would be my bet. And compared to these "very early" planes, the 109F, Spit V, and C.202 are all "uberplanes". Its all a matter of perspective.
Just my opinon
