There aren't a lot of roleplaying systems for the Old West (Victorian era USA), but there don't need to be, because Deadlands is enough in itself. It combines just the right balance of western movie grit and style, Victorian era pseudo-science, and Lovecraftian horror. It is a superb setting overall. Magic is well presented, and well limited to keep the old west feel instead of having Dungeons & Dragons style wizards running about in leather dusters. I never even liked the old west genre, but I loved this game. Note: this review applies only to the d20 release and the original release before that, NOT the new card based system.
