Thanks for replies everyone.
From what we know of Nar Shaddaa, it is somewhat glamorous on the surface, with crime and poverty in the residential districts and lower levels. It is like Coruscant in many ways, but it should give off a more "Run-down" vibe..
As opposed to Coruscant which is dark, poor and infested with crime in mid and lower levels, Nar Shaddaa is dark, filthy and infested with crime everywhere.
the quest areas you usually go too aren't rich looking at all.
Well there are these fancy lights and holo trees everyone. Even Duros sector is full of them, which is (ironically) according to the SWTOR "codex" one of the poorest sectors of Nar Shaddaa.
I wouldn't mind if only "the promenade" and its proximity looked fancy but they just messed it up.
