A story that might be interesting to explore:
You crash land on a planet. Your ship is completely destroyed. You manage to salvage a power source and your cryo-pod. Exploring, you find a tribe of primitive aliens. They are peaceful, and share their food. You communicate with gestures and drawings in the dirt.
Suddenly a plan comes to you. You can teach them, guide them on the path of becoming a space faring species. Your cryo-pod should allow you to pause your life while you wait for their civilization to grow.
So you begin. You first teach them the concepts of basic math. Seeing that they have understood, you go back to your cryo pod, and give them instructions to wake you in 50 years. Emerging from your pod, you see a changed landscape. The mud huts are now stone, a well has been dug, and there are fields planted nearby.
You engage in your next lesson. Through each phase of mathematics, you see the civilization advance around you. You see viscerally how the knowledge of the society enables it to accomplish great things. The game culminates in the emergence of a space faring civilization, which with your help constructs a new spacecraft. Along with an alien crew, you embark on your new mission to return to Earth and forge an alliance with this newly discovered alien civilization.
