Electronic Arts has announced that their digital distribution platform known as Origin will be offering third-party PC games starting next month. The first group of publishers to sign a deal with Origin includes Warner Bros., THQ and Capcom.

Hit titles like Batman: Arkham City and Saints Row: The Third will be the first to launch with more games joining the mix over the next several months. Origin already has over 100 EA games in its library and adding more publishers will only strengthen the service’s desirability against Valve and their Steam platform.

“Since launch, we’ve had overwhelming support from both publishers and developers across the gaming industry, recognizing Origin as an opportunity to deliver more of their great content straight to consumers across the globe,” said David DeMartini, senior vice president of Origin at EA. “We’re excited to welcome Warner Bros. Interactive Entertainment, THQ and Capcom as the first publishers to offer their games via Origin.”

Just last week we reported that Origin had over 5 million users but according to EA, that’s old news. Figures mentioned in today’s press release indicate the service now has over 6 million registered users. That's not bad considering EA launched Origin less than five months ago at the Electronics Entertainment Expo. This figure will likely swell over the next few weeks as users flock to the service to play Battlefield 3.

In addition to the new licensing deals with these three publishers, Origin users also have several other games to look forward to this year. Star Wars: The Old Republic, an Origin digital exclusive, is scheduled to launch on December 20 while the next version of The Sims and Mass Effect 3 will likely drive plenty more users to EA’s digital storefront.
