"In Huttese, the name translates into “Glorious Jewel”, and the planet more commonly called Nal Hutta is considered a paradise to the gluttonous tastes of the Hutts. To anyone else, though, the planet is a living nightmare—a disgusting and dangerous place to visit, and an unthinkable place to live. Current Underworld slang has shortened the name to a simple ‘Hutta’—a place where more civilized people threaten to send their children if they misbehave."
UPDATE #2: The latest developer blog at SWTOR.com features a Senior Environment Artist from Bioware, Alex Thomas, who discusses "Creating the Poluted World of Hutta." Excerpt below"
"Pop quiz: If you had the chance to contribute one thing to a game like Star Wars™: The Old Republic™, would it be A) a new Rancor design, B) a quest for constructing your first Lightsaber, C) new Sith Force powers, or D) six paintings of mud? If you said “D”, you might be an environment artist or have low self-esteem!
Luckily for us environment artists, Star Wars™ has an almost limitless supply of amazing planets and environments to get excited about. It’s hard not to get excited when it sinks in that you’re working on an icon like Korriban. Of course, for a well-known planet like Korriban visual reference is abundant — we all know what it should look like. But what happens when the designers want to create a planet nobody’s ever seen before (is that even possible)?
That turned out to be the case with Hutta (aka Nal Hutta) when we started production. In fact, the Wookieepedia entry for Hutta now uses an early screenshot from The Old Republic as the only image available. Hutta is the home world of the Hutts, which you may recall as the incredibly notorious species of slimy crime lords from the movies, and is integral to various class stories in The Old Republic."
