stupid idea: Imagine Blue Archive but Kerbal Space Program.
Let me explain, instead of sending students to the battlefields and faping on their 3rd party works, why not send them to into space?
Hum...
From going to launchpad (aka school yard) to the moon,
They will embark to journey of an amazing adventure, endless exploration...
Assemble rockets, planes, space stations, planetary bases, fully automated colonies,
and complex trajectories that nobody can solve.
Send your students to unknown and dangerous places (imagine sending lolis to a solar system grand tour lmao).
And...
i lost the plot...
But you get the idea.
