Any other company would be charging at least $20 for such excellent content. It evokes sense of wonder without being "gonzo," conjuring a sense of myth and a sort of "Fey wilderness/woodland" setting with interesting situations and encounters, mini-sceearios, fascinating characters and ambience.
A lot of RPG products offer encounters and settings, but all too often they feel like they're from a generic fantasy land. This product drips with atmosphere; the author doesn't just develop generic situations -- he is immensely creative and gifted at creating places that burst with story potential.
I was so pleased that I purchased all the available Rosethrone products and will be keeping an eye out for anything else from the same company.
