It's not exactly fair to review a playtest, but I'm doing this to give those who may be interested in it an idea of what Entropy is about. Entropy is going to be released as an OGL rules system. It plays like Savage Worlds with a bit of Star Wars SAGA Edition thrown into the mix. The author is very responsive and open to criticism. Everything down to the cover of the book is up for debate with the testers. I recommend getting in on this. And as a note, the fifth star will be forthcoming if the final release has good production values, everything else (rules, prose, etc.) are just great.
