This is space cowboys...
The idea is to create a space punk genre.
This genre is heavily based on the animated series. Cowboy Bebop.
It takes place in the Sol system yes our solar system. Earth was at its height of technological advancement about 100 years ago.
Space Gate technology was perfected that allowed travel between far reaching colonies and mining stations.
Earth Corparations and govement controlled most aspects of space until the Gate Tragity which made Earth basically uninhabitable.
Technology growth was slowed. Corporations and Colonies fight for control.
