This is pretty good Zoomba. Quite a good plot. I'm not a game person, so what I get from this probably wouldn't say anything that could be of help. However, looking at this through the eyes of someone who loves science fiction movies, books, it would be intriguing and I would want to read it.
I would however want to know more details in between the war, the new discoveries, focusing on one person, or a tribe or someone, who would be the "star" for me to root for. And how what is happening is affecting this person and how he/she is handling it.
I guess if I'm understanding it right (forgive me if I'm not) what you've written so far is the history? And going forward is what will be the game to be played? And so then you will have a figure to focus on to be the main role in this game story? Nice. It's beginning to make sense. I can't wait to read the rest!
