The official servers were shut down on December 15, 2011.
The ten species that were available to players included: Human, Twi'lek, Zabrak, Wookiee, Trandoshan, Rodian, Mon Calamari, Bothan, Sullustan and Ithorian.
There were nine professions in the game after the New Game Enhancements(NGE) (34 pre-NGE): Jedi, Bounty Hunter, Smuggler, Commando, Spy, Officer, Medic, Entertainer, and Trader. The trader was further divided into four separate professions: Domestic Goods (tailoring and cooking), Engineering (droid and vehicle crafting), Structures (shipwright and architect), and Munitions (weapons and armor crafting). Progress in these professions was divided into three separate experience source groups: combat, crafting, and entertaining. In addition to these professions, a character could also pursue three optional (they could be advanced in regardless of chosen main profession or progress in it): Pilot, Chronicler, and Politician. During the Pre-NGE, customization was easier due to "skill points" which could be spread amongst many different profession trees.
