What separates this game from Stellvia which is already a big open Sci-Fi?
Higher tech ceiling? Bigger nations at average?
Or just there are enough people who are burned out with that one?

Anyways, I may just recreate my Morte Empire.
We beleive magic is bullshit but if we see it too many times then we might start shitting our pants and develop countermeasures.
Otherwise they're a small civilization with only a few systems that only recently started looking outside their zone.
I may also create NPCs for the various races they had been at war with.
