The Crystal Space engine was dropped in favor of Ogre (which took "a lot of work" to port the simulator over), this was done because Ogre had "better features" and supported things like the "Caelum sky system". Interestingly enough Crystal Space development stopped not that long after (after they put out a 2.0 release), and the engine is now discontinued, Ogre is still being developed.
