Hello, I purchased the Champions 5th Edtition book this afternoon and have only started reading it. I have played RPG's for many years but never got around to Champions. My question is this: Is this a self-contained game or do I need other HERO System books to play? I know if I keep reading, I'll find the answer on my own, but if someone here could tell me sooner, I can try to get the book(s) I need that much more quickly. Thanks James
