My players had a blast with this. It definitely ran longer than a half-hour, especially given all the "how to play" explanations that happen at the table with new players.

I added a larger encounter with the bandit as well, and ran it for a group of level 2 characters, but the structure of the adventure is simple, but effective.

By the time the end of the adventure rolls around, players have a good sense of what they can do in the game. Trying to convince Stonepaw to hold up his end of the bargain ended up being the high point of the night as each player tried to put their characters skills to the test. Many fails were had, and finally they resorted to good old fashioned theft.

With the wizard.
