I have no experience in programing a game, but I have used Unity and Roblox before to design something. I just finished brainstorming a sci-fi game I want to create and make it into a game and sell it to many game companies. It's a science fiction game very similar to Half Life, Red Faction, and Mass Effect. I am deciding to make it into an action-adventure RPG. The main protagonists are aliens who are defending themselves against the antagonist USSF (United States Space Force) who don't want their planet Avrochros to become a colony.  The aliens all have Greek names due to the fact that of Greek mythology where the planets are named after. The goal of the USSF is to demonstrate their super might to colonize another planet for the purpose of military strategies. Once the USSF landed inside the planet, they were expecting the planet to be empty after studying its external composition for over a few years. They went in with their hardware ready to build their own military bases. Little do they know, the aliens had a zero tolerance for colonialism and fought back with extreme valor. The war lasted for one month but it changed the lives of millions inside Avrochros. In the end, unity and might displayed, all thanks to these small group of people.  Important facts about this game. 

1. The protagonists are aliens with Greek names
2. The locations all have Greek names
3. The antagonists are all humans
4. Only one human is a protagonist, and she is a representative from Mexico. 
5. Genres are Sci-fi, RPG, and action-adventure. 
6. Inspired by Red Faction 1, Mass Effect, and Half Life

P.S. I want to share these ideas with indie game developers.
