The sim is a tool.
Its purpose to learn the selective radial scan. The interpretation of instruments. And checklists.
A generic sim does for the purposed of basic IR training does this just as well as one that has tarted up to look exactly like an aircraft.
In actuality it is rare for your test aircraft to be exactly the same as ones you trained on - never mind the sims.
Nice sims are generally ones that don't break down, are readily available and aren't nearly as expensive as the aircraft themselves.
The shineness factor is purely a bonus.
Not to mention that is not the tool but the craftsman that is paramount.
