Hexx: Heresy of the Wizard

First of all, if you're looking for the 3D shooting game with a similar name, you'll want to try Hexen instead. Now that THAT is out of the way ... Hexx is a 3D RPG in the same genre as Ultima Underworld (which appeared approx 2 years before Hexx) and other real-time 3D dungeon crawlers. It is apparently an update/sequel to the game Bloodwych. The graphics, sounds, and animations are all done pretty well here. You also get a full party of characters (I imagine in the full version you can generate them yourself) instead of just playing as a single hero. Combat seems to occur automatically when you click the battle graphic.
