Hello developer brothers!
I need help developing the story of my game, because every time I reread my script, I get confused with the plots and run out of ideas.
The bases of my story are as follows:
You are in a spaceship. Humanity has left the earth to explore the universe, but has become so far away that it has lost all contact with it, therefore, the earth is a very distant memory.
What else can I add to the story?
How can I make it interesting? 
Well 2 sentences isn’t really a story. I’m gonna need to know more about your game if you want my help. What’s the game about? Is it story-based, are there any characters in it? What’s the setting?
Space travel could potentially take a very long time. So long, in fact, that perhaps spaceships need to have independent ecosystems to sustain a human population. Future generations will be born, live, and die for a mission they had no choice in being a part of. They struggle for a sense of purpose with one faction clinging to the traditions and artistic achievements of Earth, and another faction attempting to delete the archives to free themselves from the dogmatic influence of the past…
