RS1 - Red Sonja Unconquered

This module comes up pretty frequently on the secondary market and it always seems to go for a higher price than other modules from the same error. I was on a hiatus from playing by the time this had came out but picked it up before the prices went as crazy as they have. I have also never had a chance to read it all the way through. I find myself wondering if the module is that well done or if it is being bought up by fanboys for the fine representation of Res Sonja on the cover.
