I GMed this scenario at a convention. Other people have gave in depth reviews, I just want to add my voice that this is an excellent mod. As suggested it is very challanging which I found to be a nice change of pace.
Although this could be considered a dungeon delve, it really does not feel like it because of the well balanced addition of role-playing oppertunities. Furthermore I would like to comment that the role-playing oppertunities are very good, and feel more then just nostalgic due to the inclusion of real benefits or concequences depending on how it plays out.
To top it all off Gen. Goldfrap lost his panties on this scenario, can't get much better then that.
