If I was not telling you that it is a simulator issue you maybe didn't reply like that.
I came here to ask one question about a REAL procedure without considering it's a simulator.
Maybe you don't know the abilities of the simulator today and that's why you call it "game", you can absolutely do a classic IFR flight with a GA aircraft all over the world.
You can do a lot of the real procedures and I'll give you some details:
SID, STAR, Holdings, prescion and non-prescion approach, DME arc and much more.
P.S. The NG's engines have an IDG and not a CSD (I think at the classic have).
