MMO developer Sony Online Entertainment launched its first Facebook game, an adaptation of popular turn-based strategy game PoxNora with new social features.

Originally released in 2006, PoxNora is part turn-based strategy game, part collectible card game, and is set in a fantasy world of creatures, relics, and spells. The game was originally developed and maintained by Tucson, AZ-based developer Octopi, which SOE acquired in 2009 and set up a Tucson studio around.

Since the purchase, PoxNora has brought in more than 2.5 million registered accounts. SOE hopes to expand that userbase to a wider social networking audience by including new features in the Facebook version like the ability to invite friends and post updates of accomplishments.

SOE, which typically developers PC and console MMOs like Free Realms, EverQuest, Star Wars Galaxies, and many others, says it plans to create more games for the Facebook platform based on both existing franchises and new intellectual property.

“The Facebook platform offers gamers a new and powerful way to interact with and tap into their social communities,” says SOE president John Smedley. “With the launch of PoxNora for Facebook, we are leveraging the expertise SOE has gained bringing entertainment to the online gaming community for over 10 years.”
