I am sorry if this was already discussed in these forums. Reading about the Babylon 5 I could not determine whether it is a stand-alone product or if it requires the DnD Player's Handbook like other D20 products in the market. What I mean is: if I buy the B5 RPG book, do I get a complete starting game or do I need additional rulebooks? I'd appreciate if someone could shed some light into this. Thanks.
