Why I Like Zarcana Better - Andrew Looney gives his reasons for preferring his original Icehouse/Tarot game over the redesign:

To judge from reading Jake's essay on the redesign of Zarcana into Gnostica, the newer game is so totally superior to the original that no one would ever wish to play Zarcana again. I went along with this thinking during the decision to include Gnostica, and not Zarcana, in Playing with Pyramids, since it only seemed appropriate to include one tarot card game in the book and I wanted to give Gnostica a chance to find an audience with as little interference from its predecessor as possible. However, after giving the New Kid on the Block ample time to impress me, I have come to the conclusion that I greatly prefer the original game. As a counterpoint to Jake's article, here are my reasons for disliking Gnostica.

It's frustrating - I have still played neither game because of my reluctance to possess a Tarot deck.
