Interstellar Pig = Cosmic Encounter?

Ron Hale-Evans has written a very interesting article about the Interstellar Pig in the Seattle Cosmic Wiki. Interstellar Pig is a book (mentioned here before), which features an interesting game as it's main theme. The game, says Ron Hale-Evans, bears more than passing resemblance to Cosmic Encounter.

If you've read the book, go read Ron's article (and comment on it, it's a Wiki after all). I'm now quite curious to read the new sequel to Interstellar Pig: Parasite Pig. Unfortunately it's not available in libraries and probably won't be unless it's translated in Finnish, which means I'll have to buy it if I want to read it.
