As far as the math goes, I agree that you could probably do OK with Orbiter with an elementary school level knowledge of math but has anyone seen the show, "Are You Smarter Than A Fifth Grader". I rest my case. :lol:
Well, in 2005 I proved an 8 year old kid can bring a DG to circular orbit.

The general gamer crowd just doesn't like anything with a steep learning curve like Orbiter. They want something you can load up and be playing in a few minutes.
My experience says that Orbiter is plain too cool for kids.
Many of them are not allowed to drive dad's car at home, but with Orbiter they can pilot a multimillion dollar spacecraft, and no one will complain if they crash it.
The boring part for kids is when they learn about MFDs, and instruments, but after that they see it is worth to learn.
Once in orbit I recall that the nicest mission was when you had 2 DGIII in front of each other, separated by 100 meters, and they had to EVA the 4 astronauts who had the names of school mates, as one DGIII had engines disabled. It was a rescue mission. DGIII MMU had HUD display similar to DG when docking and that was nice practice for them about maneuvering and docking.
They had about 45 minutes before night came.
It was not a contest about who did it first and there was no limit of trials. The reward was a pack of cookies if they saved all the kids. All of them enjoyed cookies at school.
