Stargate Worlds

It's a Stargate Verse Massively Multiplayer Online Role Playing Game. It's not out yet, though. One faction consists of Free Jaffa, Stargate Command, and Asgard, while the other faction consists of Loyal Jaffa, younger and smarter Goa'uld System Lords called the New Mind, and bad non-Tau'ri humans called OP-CORE.

Wait, WHOOPS! Cheyenne Mountain, the company which was formed just to develop this product, has gone bankrupt, and it is now unlikely that Stargate Worlds will ever be released. Nothing to see here, folks. Move along. -

It provides examples of:

 * Cool Gate: It's set in the Stargate Verse, take a wild guess.
 * MMORPG: Obviously.
 * Neglectful Precursors: The Ancients show up, right?
