Gamebryo, even if you don't know it. It's a studio owned by Emergent Game Technologies, crafting middleware tech for tons of companies like Bethesda and Square Enix, whose biggest claim to fame is its Gamebryo Lightspeed engine, used in "over 350 games so far." And today the studio, along with the rest of Emergent's properties, including its IP (whole or in part), were put up for sale.
The sales of asset notice comes from Gerbsman Partners via a post on the Blog of Intellectual Capital and details the current state of Emergent, a company which managed to lose revenue in the ballpark of $30 million since being founded in 2005 on through 2009. This year, the company actually showed a bit of profit, albeit a relatively small amount, nothing that could get Emergent back into the black.
What's unclear as of right now is the future of Emergent: it hasn't filed for bankruptcy, but one could assume that selling all of your stuff means you're getting out of the business for good. We've contacted Emergent for some additional info and will update accordingly.
