The iFly is fine. I enjoy it quite a bit. But it’s a MAX not an NG. Fortunately, it has its own thread:
As for the 737 MAX, it’s more than a little interesting that Boeing chose PMDG to develop Boeing’s new “Virtual Pilot Tool,” with the first model supported being the MAX lineup. Make of that what you will, but it explains why PMDG paused development of their own MAX for the consumer market. If/when they ever release it for the rest of us, I’ll buy it.
