Star Wars: The Old Republic is a massively multiplayer online role-playing game (MMORPG) based in the Star Wars universe. Developed by BioWare Austin and a supplemental team at BioWare Edmonton, the game was first announced on October 21, 2008, at an invitation-only press event. The video game was released for the Microsoft Windows platform on December 20, 2011 in North America and part of Europe. Early access to the game began one week before release, on December 13, 2011, for those who had pre-ordered the game online; access opened in "waves" based on pre-order date.
Although not officially disclosed, based on estimates, it is one of the most developmentally expensive games ever made. The game had one million subscribers within three days of its launch, making it the world's "fastest-growing MMO ever", though in the following months the game lost a fair share of its subscriptions. The game is no longer subscription only and has a free-to-play option. The game was met with positive reception upon release and has received several updates and expansion packs. Several books and comics based on the game have been released. It is estimated that the game made $139 million in additional revenues, in addition to the subscription income, in 2013.
