I would say its partly mirrored.
Sud Avation SE 210 Caravelle series (III, VI-R, VI-N, Super 10B and 12) were one of the most popular planes in AM. With over 2000 sold in every single world thats between 1964 and 1984, Super 10B definitely supposed to be a handy plane to own in AM, but not reality. And For SE 12, its sold over 1000 in every world thats in between 1970 and 1990 too.
But the problem is : AM is using maximum range, You can't load a SE 10B with 104 people and flies 1667nm or a SE 12 with 128 people and flies 23xxnm......
Well, I guess that little simplicity is the charm of AM if you think about it. You also have to consider that there were aircraft which never "officially" entered service in the real world. But we are playing things as if it was a free world economy, and thus, it does provide for an interesting experiment based just on simple numbers.
Examples I can think of were:
CSS-12 (only one built, flew around for some 10 years, I think it set an altitude record.)
MD-12 (No, not that one proposed by MDD, but the Polish one, LOT tested it, the pilots liked it, but was seen as too uneconomic for it's time, opted for IL-14).
The Constitution (was meant for the military, never flew for the airlines I believe)
130 seat AN-10A, never flew, actual type was grounded in 1972 after crashes involving the wing base as far as I know.
Tu-110, an experiment to see if anyone was willing to buy a variant of the Tu-104 with four engines, never went far, though the few built stayed in service with the VVS I believe as a plane that did experiments.
BZ-308, it was an airliner built to go across the Atlantic ocean, I think it got to prototype, but no one bought it.
And if you wanna bring MTOW into this, it would also be highly unlikely for a IL-12 to travel with a full load of 21, in reality, it had some engine issues, it was often used on routes with only 18 seats filled. There are just too many aircraft in this game to just simply regulate to begin with.
