I'll agree to an extent.
My two biggest complaints about home simulation programs are that:
*They don't have the same tactile feedback as a real plane;
*I keep having to untrain self-taught instrument pilots - that is they're looking at the gauges instead out the window.
Having said that, they can be good procedures trainers under the guidance of an instructor. Make sure you coordinate with your instructor so you get the most effective use of your time.
