One thing that has always bothered me has been our own system. Every single planet is habitable...that makes absolutely no sense at all. Only the Corellian System has a handful of habitable planets, and the reason for that is because it was "man made". It is not a naturally occurring phenomenon, and is supposed to be unique in the SW universe. So...why do we have so many?
I think we need to re-align our own system to something a bit more manageable. I think at most 2 habitable planets, with other planets have various forms of habitability that can be played with. We haven't done much with the system information as of yet, with lots of areas to expand, so it would be best for us to consolidate things and focus only on a few planets to truly flesh out.
