I want tons more Death Stars.
Seriously THIS.
Imagine a Star War where the Galactic Governments have all collapsed and individual Star Systems have their own cloaked superweapons ready to demolish whole worlds if they themselves are attacked.
It would be a powerful metaphor for the Nuclear Arms problem (outside the superpowers).
It would also remove their status as a one film at a time threat. If there were lots of little systems with their own cultures and grudges it would lead to some interesting characters and situations. The only way you could reduce the power of a large Galactic Power would be to give the smaller systems the same firepower the Empire used to have. It would lead to some fun universe building too if we got to see these regimes as individual set ups and not sided with one group or another.
More like Dune but with added fun.
