Today, it's more about storytelling and less about making it unique. Seriously, apocalypses, invasions, wars, catastrophes, everything has been milked. you can try to scrap themes that have not been, but in the end you start to understand that there were reasons for that. It might just be plain boring, or it might be pretty dry and you can't really expand on it without a lot of damage to the plot. I guess what I wanted to say was: Bysicle was created a long time ago, just adapt it and use the right materials. And of course make it look pretty. Everybody loves pretty things, even if they are useless.
