For a sim that didn’t require me to drop bombs on people or shoot down an enemy I was having a blast. The missions vary in length, difficulty, type of equipment and other parameters.
Some are acts of fanciful flying (landing a stunt plane on a moving bus) while others are a challenge to your proficiency as a serious IFR pilot. The range and types of missions are what make them appealing. There were times when my palms started to sweat and I could feel the tension building in my shoulders.
