Star Wars: The Old RepublicOver one million people have registered to play Star Wars: The Old Republic less than one week into the game’s launch, making it the fastest-growing subscription MMO (massively multiplayer online) game in history, according to developer BioWare.

“We likely had the largest one-day subscription account registration process in MMO history — over one million people are now registered players of the game, and the number is growing rapidly,” say BioWare co-founders Dr. Ray Muzyka and Dr. Greg Zeschuk on the game’s official blog.

“As you might imagine, this presented a huge strain on our infrastructure and systems,” they add, “but the good news is that we seem to be through the worst of it now thanks to folks working hard all day to serve our community.”

The developers say they are also working to resolve the issue of server queues, claiming it’s another side effect of the huge demand for The Old Republic. “We were definitely anticipating a very high load but if anything the demand for the game has only exceeded our expectations.”

To date, BioWare says players have logged 28 million hours in the game – roughly the equivalent to watching all six Star Wars movies two million times. They have also created more than 3.8 million characters, including 510,000 Jedi Knights and 550,000 Sith Warriors. BioWare says players have averaged well over five hours a day online and have killed more than two billion non-player characters in the eight days since early game access began.

“Everyone at BioWare, EA and LucasArts is honored — and humbled — by the stellar response from our fans,” says Dr. Muzyka. “We’re going to work together closely with our community in the weeks, months and years ahead, continually serving our audience with regular delivery of compelling new features and content.”

BioWare has already given a sneak peek at the new upcoming content for the online role-playing game, which includes a new Flashpoint and an expanded Operation. The new Flashpoint will take place on a brand new world, the developer says, while the new Operation will take the existing Karagga’s palace scenario and more than triple it in size.
