By "transition," I meant that other developers started making products for X-Plane, too. I don't want Captain Sim to just stop making products for FSX, I was just wondering if they can also make some products for X-Plane.

To me, Microsoft's flight simulators are more of a game than a simulator because they use known performance values to try to imitate aircraft flight behavior; X-Plane, on the other hand, uses aerodynamic formulas to try to predict aircraft flight behavior. This means that, with X-Plane, you can expect accurate aircraft behavior for any flight situation. With Microsoft's flight simulators, you can expect accurate aircraft behavior only for flight situations that have been tested in real life.

I'm not trying to bash Microsoft's flight simulators, I'm just trying to provide my reasoning for why I think that Captain Sim should start developing for X-Plane. I think that I understand the business aspect of this decision, though, so the decision is with Captain Sim. I just wanted to make suggestions.
