So I'm interested in starting a SW campaign(have been playing and DMing D&D for seven years now) but I've noticed there are a lot of books out there (with the Saga edition looking like it's separate from what came before but I'm not clear on what the differences are). Now I want to make life easier for my players and I know how much time they can spend on choosing their race - the Ultimate Alien Anthology looks capable of giving them enough races in one book but it's not Saga Edition, will there be compatibility problems if I allow them to choose their race from there? Same question applies to the Arms and Equipment Guide. Also, I'm guessing that for fluff purposes the WEG books are still good (Cracken's Rebel Field Guide looks very interesting). The campaign will have the players start as an independent rebel group and what they do from that point on depends on them.
