Sorry, should've clarified - they realised two Collector's Editions, one Lawful Good, one Chaotic Evil. They came with a ring and a little sculpture, if I'm not mistaken.
Edit: It occurs to me that this explanation makes it sound like only 2 copies of the Collector's Edition were ever made. Oh well.
Ohhhhh, ok. So the different alignments are just different collectors editions. I thought at first that they were different versions of the game.
