This is probably one of the single best resources I own as a Game Master. This book gives almost everything a GM needs to create a complete adventure for a night of fun. You can pick any of the 177 maps and just roll randomly to fill the adventure with tons of unique and interesting encounters and events. The level of creativity the author went into is truly mind blowing to me. Whether I want to just throw together an adventure for the evening, or want to spice up a detailed campaign this book is extremely useful. The reasonable price is an added bonus as well.
