All the planets are bad in this game. The overall design from day 1 was bad, at it's core they did it wrong.
Nar Shadaa was my biggest dissapointment though. A real casino where you can do at least 1 friggin gambling minigame? NO
An actual dance club that had more than a couple NPCs dancing nonstop and a band? Nope. Cant interact with anything or do anything.
All bad. Just a bad game all around. A linear, go here, collect this, kill this, nothing to do, no flare, no charm, nothing more than the bare bones junk. There is nothing special in this game that sets it apart from anything else besides the voices and that gets old after the first character.
