From the RPG description here on RPGGeek: Advanced Quick20 isn’t really all that advanced. The game is designed for experienced GMs who want an easy to play system where you can generate characters quickly, explain the rules in a few minutes and get down to gaming. It’s also a high trust system. That means it assumes that the players are there to help each other have fun and are willing to compromise for the sake of running a good session. The rules provide a rough level of balance, but I’ve left quite a bit for the group to determine. How far can you stretch a role? What exactly can you apply advances to? What are the limits of the magic system? I have my answers for each question — but they aren’t always going to be the same as yours. Use this book as a starting point. Don’t worry about the rough edges too much. As you play, you’ll find solutions that are comfortable for you.
