Thanks! Obviously I skim read right past that part in the manual. Have you found that any of the introductory free games can be won via one character, or have you needed at least 2 or 3 characters? I tried one, but got my backside handed to me rather quickly!
Four characters is what you're allotted. This is mentioned in the "Characters" section of each game's rules, except The Sorcerer's Manor--no number is given, but go with four characters there, too. Unless it's stated otherwise, go with 4 characters in every game.
