The issue is that Nar Shaddaa was always an awful, dirty place. In the KOTOR games it was one of the planets you visited, and was nowhere near as neon-shiny as it is in this game.
They were definitely channeling Bladerunner / Cyberpunk in their design
Well that's one of the problems too. The brown-rusty glow is really bothering me. In every video game that Nar Shaddaa appeared so far it had black-grey colour tone.
It is not that I don't like Bladerunner, I love it... it is just that they shouldn't have messed up the previously established Nar Shaddaa.
