I have used Flight Simulator since 1995. I can see where you are coming from, but Flight simulator is a very helpful tool not only for IFR practice but also a tool, if used right, that can help you become more confident in the cockpit as a student pilot. It helps people become familiarized with the aircraft systems and how airplanes work. it shouldn't be used for training since it is not FAA approved but it does help either way. Some third party addons for Flight Simulator are so advanced they could just as well be used for real flight training however.
