I picked up one module out of curiosity, "Isle of the Rat Wizard"
Found it basically totally incomplete & lacking any substance.
All it had was an island with a skull mountain & one small map that was not even grid-ed out so the DM can draw it correctly or even use on virtual tabletops.
It said there was this group of Ratlings here & a village of Hallo there & that there was a hermit Ratling Wizard, in the skull mountain & that was basically it.
The descriptions are lacking in substance, and there is a sever lack of maps and even artwork.
I can't call this a game module, it's just an outline with vague ideas for one, that needs a lot of work to make it a game module.
One of the laziest excuse for game publishing I have ever seen.
