Sometimes I do something and think "what if x happened?", then I tell myself why that didn't happen and what I would have done if it did. To repeat what has been said before FS can't simulate the feeling,smells, or the heat of the cockpit on a hot summer morning. It can't simulate the feeling of stalls. I was recently doing some stalls but one was specifically intense. I don't remember how far we dropped, but I specifically remember my checklists floating off my lap. That feeling is definitely not possible in any sim.
