It would be nice if planets in systems were placed more sensible... i.e. on orbits... Also it would be good if hot planets were closer to suns that cold ones (at least as long as there is no explenation for other placement as very dense clouds etc.)
As an egzample i will give Storthus system in Churba sector... If planets in this system were really on that positions it won't last long when they all crush themselves... Also hot planet Zultagal is twice as far from the local star than cold planet Idalian.
I know that Lucas does not know that there is no atmosphere and gravitation on asteroids and other obviuos things but we should be smarter ;)
now, I don´t know if all planets are using the exact canon location in sysems, but if they do we should keep them. We are afterall playing a starwars game here and somethings should be as accurate as possible. logical or not.
