Necro bump for necro board.
I dunno how the fuck they did it, but the KotOR games had the comfiest planets I think I've ever experienced in Star Wars media (even planets which had been shown before, like Nar Shaddaa). I could totally see myself living on the likes of Taris, Manaan, Onderon, or Dantooine. Fuck, even the more rural planets (Dxun, Kashyyyk, Tatooine, Lehon) were so well-done, they had this certain charm to them. I dunno maybe it's the nostalgia but holy hell, so good.
Outside of that, Endor is pretty nice as well, as previously mentioned. Bespin, too, cozy and futuristic, mm-hmm! And Coruscant (would have loved to see this in KotOR 2 as an actual planet), can't forget that. By the way, can someone more experienced than me explain what life on said planet (Coruscant) was like for an average civilian during Imperial reign? Was it about the same as before? Worse? The only EU media (read: games) I've consumed make it seem like a completely militarized planet where the Emperor also had a piece for himself, but I know this wasn't the entire planet.
