Stargate Worlds is an MMORPG currently under development by Cheyenne Mountain Entertainment in association with the film and television media company MGM. The game is designed to allow players to interact in an online universe, based around Stargate SG-1. It is being published by the newly formed company FireSky.

So far, little has been released about the game, besides initial ideas and concept art, although one notable feature of the game recently released is that it will be completely canonical[citation needed], adhering and contributing to the back story of Stargate SG-1. CME has posted on the website that the game was expected to be released at the last quarter of 2008, but has recently changed its website to reflect a 2009 release. On January 4, 2008, a TV ad and trailer for Stargate Worlds was released. Also on the same day, a sweepstake was announced. The winner will have their likeness included in the game. People interested in the game can now register for the closed beta at the official website. Participants will be chosen by random draw and there are no restrictions on who can join.
