Inherit the Earth: Quest for the Orb is now available as downloadable trial versions (http://www.wyrmkeep.com/ite/download.html) for Windows, Mac OS X and Linux -- just like the already existing PocketPC release. Registration keys can be purchased to convert these trial versions into the fully playable game.
Also, we have made a Quicktime movie (http://www.wyrmkeep.com/downloads/InheritTheEarthIntro.mov) of the game's introduction available for your viewing.
