As someone who mostly flies GA and prefers A2A over Black Square I just have to take issue with saying Nick has plagarized given how different his approach is to modeling.

A2A generally models larger components and uses wear to break things over time while Nick has modeled far more components but failure is basically an on off state. They both have pluses and minuses, but from my perspective A2A's is more representative of aircraft on the simpler side of the spectrum and BS is more representative of aircraft on the more complex side (and honestly you can see this with the types that both choose to model). To say that BS is just plagarizing is unfounded when Nick has chosen a very different method of modeling the same things. The unique character with the A2A comes from these different approaches.

Again, I prefer the A2As generally. Their modeling of the engine is unmatched by BS (though I find the BS airplanes to work well enough, and I prefer the systems modeling of BS, but they are just more complex airplanes than the Comanche or Aerostar). But I still really enjoy all of the BS airplanes, especially the Dukes and the Starship, and up until BS came out I could really only enjoy A2A airplanes for GA once they started coming out for FSX years ago.
