Well said. And in a sim game I would say more fun is to difficult to fly aircraft. Ones who were plagued with all sort of trouble or disasters or real life draw back!
To name a few: Concorde with the annoying sonic boom and extremely inefficient
MD11 which have a small horizontal stabiliser and need to land at high speed causing quite some accidents
L1011 which are too advanced for the time they are produced
Comet which have structural design problem causing premature in flight break up
All those have some problems in real life which made them retired but in a sim world where we don’t have to care about annoying civilians or we have no worry of breaking up or fuel price those are the good old days to get memory on
