I'm hopefully trying out a one shot of Forbidden Lands this weekend with some friends. It seems like something we could roll up characters for on the day and use tables to have an adventure along the way, but equally some preparation is usually good and have prepared encounters and knowledge of what characters you're dealing with in advance is normally good for showing a new game off. What's everyone's thoughts of this? If you were running something as a one shot, would you do the characters in advance? What about the exploration and locations? Are there any good pre-done resources out there (like a set of characters) that are tried and tested (and that I could just steal)?
