The Y'Gath rock... heh, rock...
I wish I'd used them for my Yendor Consortium in "Strange Races" instead of my own Fractalians...
it was just the angelic race portrait that kept me from using them...
Also that new Orion shipset... and the Vandron... and the Cluk-Ruk (hey, their ships look PRACTICAL!), and the Dominion (the space amazons not the Star Trek ones), and the Infernal Realm, and the Tylmai, and the Vidrihne...
