I've recently picked up the Rules Manual, and was wondering if there was any reason to go back and try to find the original Core Rulebook. Obviously I've got the latest rules, but has the fluff been proliferated to the website and/or Chronicles downloads, or is that still unique to the Rulebook?
Also, the Manual seems to incorporate Rising Powers and Twisting Fates, so is there any reason to pick up these books, other than fluff?
