Imagining Your Game

I originally was going to do a game with astronomy and have the player learn about the constellations of the night sky and at which times they appear thought out the year.

In this class I learn why the the stars are up there and other astronomic studies. But, Mrs Stalnaker is asking me to do a game with Civics so I don't know...
