There's a ton of different third party game engines to license these days: The Unreal Engine, the Source Engine, Gamebryo and others. Now developers Digital Extremes have quietly revealed on their web site that they are providing their own in-house technology, the Evolution Engine, to third party developers.

Digital Extremes, which used Epic's Unreal Engine for most of their previous projects, created their own Evolution Engine for their last major stand alone project, the 2008 third person action game Dark Sector (which was ported to the PC a few months ago). The company's Evolution Engine web site goes into detail about the various features of the technology which can be used for the PC, PS3 and Xbox 360 platforms. The page does not include a price point for licensing the engine; presumably that info comes after prospective buyers sign an NDA. It should be interesting to see how many clients use Digital Extremes' technology, especially in such a competitive market with tons of other middleware choices.
