This product wasn't exactly what I was expecting. The product details steps you can take to create a campaign that doesn't fall within the standard medievil theme of AD&D. They give numerous examples such as campaigns heavily influenced by ancient Rome or a Lost World where conquistadors ride dinosaurs. I had thought it would have more material applicable to DM skills at the table but I hadn't researched the product well enough.

If your having troubles coming up with a unique theme for your campaign and want something really different this might help you. If that's not what you are looking for then this product will be of little use.
