The approximately $200 cost of RC flight simulators isn't unreasonable to me.

What is unreasonable are the upgrade policies. Upgrading to a new version of a simulator rarely makes economic sense. I have no intention of spending $200, and then having the product become obsolete as little as a year later. If I could buy a simulator, and then be guaranteed that upgrading to new releases would never cost more than, say $75, this would be a big incentive for me to buy that simulator.
