RE: Disappointed with G4 sim
Most of the things stated above can be adjusted, tweaked, etc., e.g. the views, more so than any other sim on the market.
It's a pretty "deep" simulation once you get into it, and neither 10 minutes nor several weeks are enough to learn all that is there.
Once you start practising maneouvers that would destroy your real plane while learning ( e.g. canopy out hovering, torque rolls etc. ) the sim gets to be very "interesting" though it is never a substitute for being out at the field.
