I've been a roleplayer for the past 35 years, and this is hands-down the best boxed set for instructional roleplay use I've ever seen. And it's good for extended play, as well, I gave this set to a friend's son and he's been able to round up three friends and they've played using only this set and the free dowloads from Paizo.com for four months, and they're still going strong. Recently purchased another for myself and have plans to give it to another kid of about the right age.
